Material Definition Please Help

Good morning,

 

i thank you once again for the availability you offer us whenever we have our concerns...

indeed i have been trying for more than three months to simulate the behavior of Lasche whose real dimensions are below with CREO but my result are still not Validated because the Stress Max that i obtain from my simulation is much higher than the Tensile yield of the material used.

You are not using the case of two holes. (two hole effect is stress relieving)

In plane normal stress = F/A = 33KN/(18*3.2) = 573MPa

Use material at own risk. I approximated from the ASM Atlas of Stress Strain Curves. Pg 85.
