Abstract: Friction stir welding (FSW) is a relatively new joining process that is presently attracting considerable interest. The FSW process was developed at TWI (The welding institute) in 1991. Friction stir welding process is a solid-state joining process with the potential to join low melting point materials, particularly aluminum alloys. The surface finish of welded joint is very good in friction stir welding as compared with other welding process. In the present study, a finite element heat generation model in ABAQUS 6.14 was developed to estimate the amount of heat generation in friction stir welding of aluminum AA6061-T6 plate. The study was focused on numerical.....

Abstract: In this papera hybrid multi-scale epoxy composite reinforced with conventional carbon fibre (CF) fabrics surface-attached with hemp fibre carbon nanofiber mats is described in this paper, along with its fabrication and mechanical properties. The composite is reinforced with carbon fibre and hemp, two sheets were fabricated, one with CNT and one without CNT and is prepared using vacuum bagging method. Several tests such as tensile test, bending test were performed and results were calculated. The bending and tensile analysis of multi-wall carbon nanotubes (MWCNT) reinforced sheet core sandwich composite plate of HEMP and Glass fiber has been performed based on the higher-order shear deformation theory using finite element formulations.

Abstract: The Main Aim of This Paper Design and Fabrication of a Human power flywheel motor (HPFM) is to get maximum energyin a minimum amount of your time. The word tandem drive means double pedal in the machine. The main component of this machine is a flywheel, pedal, chain sprocket, shaft, freewheel, pump, and gear. The machine is extremely simple and cozy, it is often easily operated by either males or females. The machine is economically viable and it is often operated by skilled and unskilled people. In India, most individuals are affected by electricity. To overcome this problem, we select HPFM, which operated manually. This machine is used in so many applications......

Abstract: Foundation settlement is a difficult issue frequently experienced in structures; the whole structure may collapse if built on poor soil without proper site investigation. Therefore stabilization to improve the engineering properties of soft soil and reduction in construction constraints is necessary. Undisturbed soil samples obtained at depth of 1-2 metres were blended with Portland Limestone Cement (PLC) and Residue from Spent Calcium Carbide (RSCC) and later subjected to Consolidation test. The cohesive soil was mixed with 3%, 4%, 5% and 6% PLC content by weight of the soil and for every percentage of PLC content, 7%, 9%, 11%, 13% and 15% RSCC by weight of the soil was added. Results revealed that there were decrease in the compression index, coefficient of volume change......

Abstract: The community's interest in recreation is relatively high but has not been facilitated by the local government. The Nipa-Nipa Regulatory Pool as a water reservoir to prevent flooding in the development area of the Mamminasata area has the potential for a tourist attraction. It does not yet have a concept of utilization as a tourist destination. This study aims to analyze the potential, program indications and formulate a development strategy as a tourist area object, the approach used is a qualitative and quantitative description based on the results of observations, questionnaires, and interviews using ADO-ODTWA, descriptive, and SWOT analysis. The.....

Abstract: The motivation for this work is the development of a reliable alternative and laboratory relevant chaos diagrams for excited Duffing oscillators. A Gram Schmidt Orthogonal-based Lyapunov exponent was utilized to indicate points as well as regions characterized by periodic or chaotic motion for the harmonically excited Duffing oscillator. A graphical collection of chaotically behaving points called chaos diagram was developed for the choice drive parameter combinations on the plane (0.07≤𝜔≤1.5 and 0.07≤𝑃≤ 1.5). Specific cases that were studied include the three equilibria (-1,0), (0,0) and (1,0) as initial conditions and two damped levels 0.168 and 0.0168. Different.....
