Tensile Test Results (simulation vs theory)

Altair Forum User

Greetings,

 

Recently I have simulated a tensile test similar to the RADIOSS tutorial in Hypermesh. 

For units, I used:

Length (mm), Time (ms), Mass (kg), Force (kN) and Stress (GPa)

I have the simulation results as below:

 

 

 

And then I compared my results with the results from the theory manual:

 

I think my results (for stress and the shape of the curve) correlate with the theory manual, but my strain seems to be one decimal place out. May I know the error? Or is it because of units?

Hi keenan,

 

I think the problem is with the units. Can you share YOUR model files?
