Abstract
The objective of this work is to numerically study the behavior of a composite material subjected to mechanical shocks. The analyzed structure is a beam glued to another, both made of aluminum. In this context, it is evaluated the tension propagation in the region where the glue is, which is made of epoxy resin, as the mechanical wave, generated by the collision, propagates throughout the structure. Thus, mixtures changing the glue’s composition is tested to reduce the effects caused by the acoustic impedance differences. To perform this study, the softwares SolidWorks 2018 and Ansys Workbench 17.0 are used. The first one to create a 3D model, and the second one to perform the simulations. From the obtained results, it is determined a maximum percentage of improvement in comparison to the decreased main stresses in the analysis for different mixtures.
