Hi,

I am running Linear static FEA in Solidworks simulation for an assembly in which all the parts are made up of ASTM A36 Steel (SolidWorks Library Material).

I usually consider only Von mises stresses as failure criterion for this assembly.

But now I want to know the * maximum tensile and compressive stress *in the assembly and its location.

1. Does the extreme values in the P1 plot indicate max tensile and P3 extreme indicate max compressive stress?

2. Or Can I consider Directional stress (SX,SY,SZ) for Tension & Compression ?

Thanks-in-advance,

AJ

If I recall my Mohr's Circle for 3D stress correctly, if all the principal stresses are positive then they are all tensile loads. Any that are negative are compressive stress.
