Sir,

 

This is my orthotropic stress limits and Young's modulus, In that solution can i use Von mises stress for failure criteria? Because each direction failure stress value is different. so How to differentiate failure stress or strain?

 

Other, Should i used Normal stress and shear stress of all 3 direction (X,Y,Z, XY, YZ, ZX) direction and compare with stress limit. 

 

Which method is correct? 

Any other method is there for simple solution please suggest.
