Hi, First of all I must say, I am a bit ashamed asking this question... Since its been a long time since I studied mechanics of materials and since I never used it in my line of work, I am trying to analyze a problem regarding this subject using COSMOS in solidworks, I have a model and I figured out the boundary conditions and the forces acting in the system. The analysis seems ok, but i have difficulties trying to remember what the numbers say... Assuming small displacements, I am using the VON MISSES criteria, as far as I remember this criteria predicts yielding of ductile materials in a good manner, first of all, is this correct? Second - how does the other criteria (shear and normal stresses in all directions) should be interpreted, and how can they be correlated to the yield strength? Thanks.
