ANSYS static structural beginner help

[Goliathmech89]

Hi everyone, I'm trying to recreate a compression test on a nanolattice cube on ANSYS Workbench 15.0, and I'm hoping to get a stress strain graph of the cube, as well as plot the compressive strength vs time graph to find the maximum compressive strength of the cube, and when it starts to buckle and fail.

I'm using static structural, and I've on large deformations. I'm using displacement on the top of the cube to stimulate the compression test and a fixed support on the bottom, but I'm not sure how to derive the graphs I need.

My next issue is that I'm currently using the default structural steel, but my actual material is an ABS polymer, but I'm unable to find the material in ANSYS library.

I'll appreciate any help I can get here.. Please feel free to ask me for more information and I'll try my best to provide.

Hi,

To be able to get a stress stain graph you will have top create a custom graph. See this link:

In regards to the compressive strength, you can get the equivalent stess vs. time and then from this you can work out the max. strength.

In regards to custom materials such as ABS polymer, I am not sure if this is a standard material model found in workbench, but I would simply create a new material and place in the properties of the polymer,

Hope this helps,
