what is the difference btw stress in von mises & max principle stress
what is the difference btw stress in von mises & max principle stress
(OP)
Hi
I want to compare the stresses obtained from Pro-mechanica with respect to the material flexural yield stress. Which stress reading (von mises or max principle stress) should I use?

Which one to use?, that depend of the kind of material (ductile -? plastic deformation failure model), Brittle (no plastic deformation basically) etc, you are using in your design.
I recommend you to have a look on:

On here you can see the differences between Von Misses, principal stress etc.
Some design codes such asme 8 ( for pressure vessel design) use max shear stress as a design method due to the fact that most of the material used for pressure vessel are made with ductile material, so max shear stress is the one more suitable for such materials.
Hopping that this explanation helps you.
