I am performing the static analysis on hydraulics component where I am using the nonlinear material properties with multilinear kinematic material model having yield ~150 ksi and ultimate strength ~210 ksi. However I am getting first principal stress as 280 ksi and von Mises(equivalent) stress ~ 240 ksi.
I checked for the directional stresses where I find the stress in axial direction as ~279 ksi.
Whether it is possible to have the stresses above the given material limit (in this case true ultimate strength is 210 ksi).
