Importance and use of composite materials are no longer a subject that should be emphasized. They offer a successful replacement for classical materials in most areas of engineering, conferring similar elastic-mechanical properties to metal or non-metal alloys with several advantages such as reduced mass, chemical resistance etc. Considering this, knowledge of the elastic-mechanical characteristics is of utmost importance. The present article aims to create a finite element model that can predict the longitudinal elastic modulus of a double-layered composite material based on the elastic characteristics of its constituents. For this, the elastic characteristics of the constituents were determined, then used in the finite element analysis thus obtaining the Young�s modulus for the numerical composite material. Also, the longitudinal elastic modulus of the resultant composite was determined experimentally. The results of the finite element model were compared with experimental values.

“…Gabriel Jiga et.al. [11] proposed a methodology to improve the impact performance and reduce the damage of vehicle body at impact speed. Repair cost at collision accident can be cut down by use of this box, several numerical simulations have been performed on different crash-boxes models in order to obtain an optimized shape necessary to reduce the absorbed energy by the side-member, the best behavior in case of low speed impact is obtained by the optimized shape of the caisson made from aluminium, filled with foam.…”

In engineering and technology safety of human life has always been a top priority. With the increasing usage of vehicles in everyday life, probability of deaths and injuries has also increased, but safety is important too. The main aim of this study is for designing an energy absorption tubes (Crush Can) of different shapes, thickness, at 10 km/hr speed and checking its performance by numerical simulation on the basis of FMVSS by using Finite Element Analysis and evaluate the result by changing design of Crush Can in the form of stress, energy graphs are plotted, by comparison of results, we can suggest that 1mm thickness and circular design absorb optimum stress and more energy than other. The HYPERMESH software is used in meshing and LS-DYNA software is used as a solver

The present study investigates the compressive deformation behaviour of aluminium matrix syntactic foam. Thecenosphere hollow filler was incorporated into the aluminium matrix to fabricate the syntactic foam using stir casting technique. A compressive test was conducted on the syntactic foam to evaluate their mechanical properties, and the results were compared with the finite element ABAQUS explicit simulation software. The plateau strength and energy absorption capacities of the experimental and numerical results show a deviation of 1.76 and 7.13% respectively. The numerical results are good, in agreement with the obtained experimental results, and beneficial in understanding the compressive behaviour of closed-cell syntactic foam.
