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?

Sure Prakash. Please let me know if you need any other files. Thanks

Hi Keenan,

 

Can you try with below values:
