I need for an analysis to use the Mohr Coulomb criteria.
I tried to use it on a simple case: a torque applied to a rod
I mesh and run a static analysis. And then I visualyse the criteria value of the center area
(The material use to calculate the criteria has the following properties: ultimate tensile strenght: 20MPa , ultimate compressive strenght:690MPa)
Firsly I visualise the Von Mises security criteria distribution:
The result is coherent as it show an high coefficient in the center of the rod which decrease when we go to the periphery of the rod.
Secondly , I visualise the Mohr coulomb criteria distribution:
I can't explain the result! according to me this doesn't have any sense?!
Is there a bug in solidworks?
Can somebody help me?
