In this study, compression test done for Ti-6Al-4V cuboctahedron cellular sample. In the experiment, by varying sample porosity number for Selective Laser Melted structure we ended up with brittle and non-linear response. Simulation is performed using Bi-Linear material model with ANSYS workbench. Different simulations are modeled to include non-linear and plastic effects in the results. Results of compression simulation with strain rate of 2.08E-03 /sec and 50% strain are extracted. The usual way of computing stress from force reaction and strain from total deformation does not fit with experiment exactly. To study the equivalent Stress/Strain directly, the numbers of solid element distributed at each Stress/Strain levels is listed and the solid density of the structure is used to transform the Equivalent Stress/Strain for finite element into Stress/Strain for cellular structure. Experimental Stress-Strain curve is compared with all the Stress-Strain curves derived from the various models described in Static Structural module.
