Title	:	An overview of Friction stir welded alloys: Microstructure and properties
Country	:	India
Authors	:	Adadande A.S.1, Naniwadekar A.M., Gaikwad S.P., Khot A.R

Abstract: FSW is considered to be the most significant development in metal joining in a decade and is a ''green'' technology due to its energy efficiency, environment friendliness, and versatility. As compared to the conventional welding methods, FSW consumes considerably less energy. No cover gas or flux is used, thereby making the process environmentally friendly. The joining does not involve any use of filler metal and therefore any aluminum alloy can be joined without concern for the compatibility of composition, which is an issue in fusion welding. When desirable, dissimilar aluminum alloys and composites can be joined with equal ease [8-10]. In contrast to the traditional friction welding, which is usually performed on small axis symmetric parts that can be rotated and pushed against each other to form a joint [11], friction stir welding can be applied to various types of joints like butt joints, lap joints, T butt joints, and fillet joints [12]. A unique feature of the friction-stir welding process is that the transport of heat is aided by the plastic flow of the substrate close to the rotating tool [13]. The heat and mass transfer depend on material properties as well as welding variables including the rotational and welding speeds of the tool and it's Geometry.

Title	:	An Overview of Radiator Performance Evaluation and Testing
Country	:	India
Authors	:	Prof. A. R. Khot 1, Prof. D.G. Thombare 2 Prof. S. P. Gaikwad 3 Prof. A. S. Adadande

Abstract: In this paper various methods for radiator performance evaluation and testing of the radiator are considered because all internal combustion engines produce heat as a byproduct of combustion and friction. This heat can reach temperatures up to 1925°C (3500°F) and can have catastrophic affects on engine components. Pistons, valves and cylinder heads must be cooled to reduce the risk of detonation. Cylinder temperatures need to be controlled so lubricating oil can maintain a protective film on the cylinder surfaces and the lubricating oil should be cooled to ensure its integrity. In addition to overheating, overcooling can have negative effects on the engine. Overcooling can reduce engine performance and shorten the engine's service life. Cooling systems are used to manage engine heat. Cooling systems must be properly designed, operated and maintained for proper engine operation and service life [5].

Title	:	Application Of Theory Of Constraints On Scheduling Of Drum-Buffer-Rope System
Country	:	India
Authors	:	Mr.Shamuvel.V.Pandit1, Prof.G.R.Naik

Abstract: The successful enterprises deliver products and services in shorter throughput time and turnover inventory as quickly as possible. Three important approaches to achieve these goals are Materials Requirements Planning (MRPI, MRPII), Just-in-Time (JIT) and Theory of Constraints (TOC). TOC is systematic management approach that focuses on actively managing those bottlenecks that impede a firm's progress toward its goal of maximizing profits and effectively using its resources. TOC seems to be a viable proposition because it does not require costly affair of system change; rather it is simply based on scheduling of the capacity constraint resources. The scheduling system of theory of constraints (TOC) is often referred as drum-buffer-rope (DBR) system. DBR systems operate by developing a schedule for the system's primary resource constraint. This paper describes the basic overview of application of TOC on scheduling of drum-buffer-rope system and the previous work carried by researchers along with brief review. Elimination of bottleneck resources by DBR scheduling it is possible to improve profit by improving throughputs, reduction in WIP inventories; improve on time delivers and better utilization of constraint resources. TOC is applicable to any kind of industry for scheduling.

Keywords: Bottlenecks, DBR scheduling, Primary Resource Constraint, Throughputs, TOC.

Title	:	Cold Hole Expansion Process for Stress Analysis and Evaluation of Fatigue Properties
Country	:	India
Authors	:	Basavaraj Kawdi1 Dr. N. Shanmukh

Abstract: Cold expansion of fastener holes has been successfully used for many years to impart beneficial compressive residual stresses. These residual stresses serve to extend crack initiation lives and to slow down growth of small cracks. In this paper stress analysis in open holes in Aluminium alloys 7050 series have been carried out with FEM approach. The Split-Sleeve process has been used wherein expansion of the hole is accomplished by putting tapered mandrel prefitted with a lubricated split sleeve through the hole. The mandrel and the sleeve are designed to generate a prescribed amount of plastic deformation around the hole that in turn creates a state of biaxial residual compressive stress in that area. A typical development of plastic deformation in terms of Von Mises stresses in 7050 Al plates were examined. Tests were carried out using plates containing plain holes and cold expanded holes in aluminium. Residual stress measurements have been done after cold expansion and after various loading conditions. Results were obtained from the FE simulation for radial and tangential residual stress through the thickness of the plate as a function of the radial position. This investigation conclusively show that a significant fatigue life extension can be obtained from a hole that is reworked using a split sleeve cold expansion after a period of constant amplitude or flight spectrum loading. The degree of improvement increases if the hole was also cold expanded during the expansion.

Key words: Fatigue, Cold hole expansion, residual stresses, split sleeve process.

Title	:	Development of Hydroxyapatite Bio-Scaffold
Country	:	India
Authors	:	Vikram Kumar1, Dr. Uma Batra2 Amit Kadam3 Prashant Mulik

Abstract: Hydroxyapatite (HAP) are particularly attractive materials for bone and tooth implants since they closely resembles human tooth and bone material and have proved to be biologically compatible with these tissues. Porous hydroxyapatite exhibits strong bonding to the bone, the pores provide a mechanical interlock leading to a firm fixation of material. It is more resorbable and more osteoconductive than its dense counterpart and in porous form the surface area is greatly increased which allows more cells attachment in comparison with dense hydroxyapatite. In present work, hydroxyapatite powder has been prepared via sol-gel technique using calcium nitrate tetrahydrate [CaNO3.4H2O] and potassium dihydrogen phosphate [KH2PO4] as precursors for calcium and phosphorous respectively. Porous scaffold was prepared by polymeric sponge media soaked in slurry of hydroxyapatite powder mixed with 5 wt% polyvinyl alcohol. After drying the soaked sponge was burnt at 1250°C, which resulted into a porous scaffold. Porous hydroxyapatite had about 63% porosity. The pore diameter is ~400-500μm and pores were interconnected. It is reported that porosity, pore size and pore inter connectivity depends upon the slurry concentration and the amount of pore size of sponge media.

Authors	:	R. S. LAVATE1, A. T. PATIL2, A. M. PATIL3, N.V. HARGUDE

Abstract: Fiber reinforced composite materials are gradually becoming more popular for several applications, either as components of elaborate technical systems, as structural elements or even as complete structures. Their main advantage over metal components is their resistance to weight ratio which is very important for many applications. The purpose of this study is to investigate dynamic analysis of the composite beam. In this study, longitudinal transverse Young Modulus, poison's ratio and shear modulus were determined by using simple formulae. The longitudinal & transverse vibrations were obtained theoretically and analytically. Numerical study was performed by finite analysis software by using ANSYS 11. In this software, the test specimens were modeled in accordance to experimentally tested specimens. The boundary conditions were applied to the model. These outputs were transferred to the graphs. Inspection of the dynamic behavior of the composite beam for various end conditions is made by both FEM and theoretical analysis.

Title	:	Experimental Setup for Hot Machining Process to Increase Tool Life with Torch Flame
Country	:	India
Authors	:	R. D. Rajopadhye1, M. T. Telsang2, N. S. Dhole

Abstract: Now days, to satisfy industrial requirements we should have materials with very high hardness and shear strength. So manufacturers are intended to manufacture such materials having high hardness and shear strength. There are various conventional methods for machining, but use of such methods reduces tool life with increase in tool wear and it results in increase in cost of manufacturing. Hot Machining can be used to decrease tool wear, power consumed and increase surface finish. In Hot Machining the temperature of the work piece is raised to several hundred Celsius above ambient, which causes reduction in the shear strength of the material. There are various heating methods, like bulk heating using furnace, area heating using torch flame, plasma arc heating, induction heating and electric current resistance heating at tool-work interface. We used torch flame method for heating the work piece. In this paper experimental setup of hot machining process is explained.

Key words: Hot Machining1, Torch flame, Tool life.

Title	:	Experimental and Theoretical Investigation of Combined Effect of Fluid and Thermal Induced Vibration on Vertical Thin Slender Tube
Country	:	India
Authors	:	Narasimha Marakala1, Appu Kuttan K K2 and Ravikiran Kadoli

Abstract: The paper presents an experimental and theoretical analysis on the study of dynamic response of a thin slender cantilever pipe conveying air at different pressures and temperature. A dynamic characteristic of a pipe line conveying internal fluid experiences mechanical load due to inertia effect of fluid, coriolis force, fluid rotation kinetic force due to fluid flow velocity, dynamic load due to inertia effect and thermal load due to hot air on the pipe. One dimensional beam finite element is used for investigating the dynamic behavior of the thin slender pipe with appropriate numerical computational method for analysis. The fundamental natural frequency of vibration is correlated with experimental and numerical method.
