Hi All,
Does anyone know where to find the von Mises stress
calculation formula that Mechanica uses? I have looked in
the documentation and the only description is:
"An equivalent stress that is a combination of all stress
components. The von Mises yielding criterion states that
a material reaches its elastic limit if the von Mises
stress is equal to the material's yield stress in simple
tension."
I am curious if it is the same as the classic von Mises
yield criterion (second deviatoric stress invariant
definition) or if it is simply some RSS calculation that
the post processor is making to combine the stress states
over each mesh element.
Thanks in advance,
lindejos
