Split Hopkinson Tensile Bar (SHTB) named after Bertram Hopkinson, also called a Klosky bar, is an apparatus for testing the dynamic stress–strain response of materials. is a commonly used setup for engineers to investigate a material’s mechanical properties. This report seeks to use Finite Element Method (FEM) to investigate the relationship of stress strain properties in Aluminum T6061 by means of simulation software. The entire quasi-static and SHTB setup will be modelled in SolidWorks and then import into ANSYS Mechanical APDL Workbench coupled with LS-DYNA for Finite Element Analysis (FEA) of the entire process. Running simulations on the FEA software, it is more cost effective compared to performing the actual Split Hopkinson Tensile Bar experiment.
