Reply To: Mohr-Coulomb Stress Safety Tool

[Pedram Samadian]

Hi,

Thanks for the clarification. Would you please check the Mohr-Coulomb criterion manually for the elements located in those regions based the predicted maximum and minimum principal stresses?

If you get a safety factor of lower than unity similar to LS-DYNA and are sure that it should be more than unity in those regions, I would suggest reducing the element size, specifically around the hole edge. Moreover, try using higher-order element types (quadratic), which often improve stress results near discontinuities.

I hope this helps.

Thanks,

Pedram
