Title | : | Numerical bird strike impact simulation of aircraft composite structure |
Country | : | India |
Authors | : | Nagaraj V, Velmurugan T |
Abstract: The work presented in this paper deals with application of explicit finite element analysis in order to predict the bird-strike induced impact damage on fuselage part of typical transport aircraft. A methodology has been developed to support the bird-strike certification of the metallic materials made with aluminum alloy2024-T4, 7075-T6. The numerically explicit LS-DYNA codes were used to simulate the arbitray Lagrangian Euler (ALE) bird model. An important part of the bird strike modeling procedure is the application of a bird replacement material with constitutive response which replicates the forces induced by an impact of a real bird. The bird material is modelled by an equation of state, with properties that match the pressure–density relations of water and air mixtures. The input parameters for the simulation have been selected as to simulate a bird strike used to verify the compliance with damage tolerance certification requirements. The ability of this work is leading to improved design efficiency and safety, while significantly reducing certification cost.

Title | : | Finite element analysis of burst pressure of composite storage vessels |
Country | : | India |
Authors | : | Shanmugavel.M, Velmurugan.T |
Abstract: An Axis-symmetric finite element model of glass fiber reinforced polymer (GFRP) pressure vessel is established by ANSYS finite element software. A parametric finite element model of Glass fiber/epoxy composites is proposed to predict the damage evaluation and failure strength of composite hydrogen storage vessels. The maximum stress, Hoff-man, Tsai-Hill, Tsai-Wu failure criteria are used to determine the failure properties of composite vessels. A solution algorithm is proposed to investigate the progressive damage and failure properties of composite structures with increasing internal pressure.

Title | : | Multi-objective Optimization of Mobile Robot Path Planning Using Genetic Algorithm |
Country | : | India |
Authors | : | Balaji A, Padmanabhan Panchu K |
Abstract: This paper proposes an idea for finding a multi-objective optimal path for a mobile robot in a given known environment from a user defined initial point to final point. The objectives considered here for optimization are, length of the path and smoothness of the path. The length of the path is defined as distance covered by the robot while it moves from one point to another and the optimal length of path is shortest path that reaches the final point after avoiding obstacles. Smoothness is defined as the number of turns taken by robots to reach the final point. Since the robot changes its pose by turning, the velocity of robot reduces which results in more consumption and as well as the time to reach the destination. First objective here ensures the distance travelled by the robot to destination point is to be minimum and the second objective ensures that the turns are minimum and thus robots need not reduce its velocity while turning. Ultimately, with the optimization of these two objectives, the robot can reach the location as soon as possible and without reduction of any velocity. The proposed idea can allow the robot, to find the optimal solution, which has shortest path and smoothest path.
Key words: genetic algorithm, length of the path, robots, smoothness.

Title | : | Ranking Of Workforce Factors Using Multi-Criteria Decision Maki |
Country | : | India |
Authors | : | Karthik.A, Jeya Girubha.R |
Abstract: To improve the production rate, the work environment, labour efficiency, reduce the delivery time, lower the production cost and even increase the product range to fulfill the customer's needs. When a choice is to be made from among several alternatives for a given industrial application, it is essential to measure up to their performance characteristics in a decisive way. Multi-criteria decision-making (MCDM) method can be effectively used to solve such type of problem. It is observed that many methods give almost the same rankings of MCDM method, although the performance of MCDM method is slightly better than the others. In this project, most popular MCDM method is considered and the relative performances are compared with respect to the rankings of the factors as engaged in industrial pick-n-place operation. It can be concluded that for a given industrial problem, more attention is to be paid on the proper selection of the relevant criteria and alternatives.

Abstract: Combining the suitable properties of metals and fiber reinforced composites, as the idea behind the application of new types of materials called fiber metal laminates (FMLs). In this article, the effect of volume percentage of fiber determines the mechanical properties such as tensile and flexural tests have been investigated and experimentation was performed. Aim of this paper is to compare the four different types of layers such as 2/1, 3/2, 4/3, 5/4 in 45degree stitched mat GLARE laminate. Essential quality of this 45degree orientation may lead superior resisting to tensile and flexural properties. The laminates were obtained by hand layout technique and specimens were cut off from wire cutting as per ASTM standards. The experimental work was done by AUTOGRAPH -50KN Computer controlled UTM. From the experimental work, tensile and flexural tests were taken and graphs were plotted between stress vs. strain and load vs. deflection. In addition to that, 4/3 layer of 45 degree GLARE laminate had superior strength than that of the other layers.

Title | : | Investigation on the self loosening behavior of hexagonal nut and nylock nut in curvic coupling under transverse loading |
Country | : | India |
Authors | : | Sathish Kumar N |
Abstract: Failure of fasteners is due to dynamic loads generally due to fatigue or self-loosening. Even partial loosening can reduce the fasteners preload and thereby increase the dynamic loads acting on the fasteners loading to increase of fatigue failure. Nylock nut has property to prevents the self loosening under vibration Such failure can be catastrophic in safety application. In this project self loosening of bolts in curvic coupling is analyzed for standard hexagonal nut and nylock nut by applying cyclic transverse load on disc after the preload of bolt. Using ANSYS AND PRO-E 3D model for curvic coupling and thread is established to study the details of self loosening mechanism of bolt in standard hex nut and nylock nut.

Title | : | Ensuring Brand Clarity and Consistency in Today's Multi-channel World |
Country | : | India |
Authors | : | Jayanthan C, Krishna Kumar N |
Abstract: Strong brands influence customer choice. A brand becomes strong when it retains its core values and purpose with time. Manifestation of these might change from time to time depending on internal and external factors. The key to combat is to have a strategic consistency for the brand to maintain its distinct identity. A brand is an intangible asset and also a critical component of what a company stands for. Brands never become icons over night and many of them have failed because they couldn't "connect" with their audience. Name of the brand, Positioning and Packaging are the ingredients to be used so that the customer is not confused and a unique and distinct identity is built for the brand. (Jagdeep Kapoor, Managing Director, Samsika Marketing Consultancy) So how do brands consistently ensure that they create their value? How can the brands change the world in which they operate? This research work has been carried out by forming and analyzing the propositions right from the foundation of environment, employing people, owning a brand name (Geoffrey consulting), strengthening brand association (Nodal Map), creating emotional branding to stay in customers' minds, tackling crisis and providing the best moments of truth to engage the people in bringing the brand into their life. All the information specified in this paper comes from a self-reported survey and is the result of analysis of the data. It is our opinion; the information presented in this report represents an insightful and valuable assessment of the state of branding which can be applied for any products/services in today's multi-channel world.
