Is Kinematic Hardening suitable for loading and unloading of steel structure?
Hi @skadam ,
Kinematic hardening represents a translation of the yield surface. This means that the elastic domain is always the same size, although the yield surface moves in principal stress space. Hence, if loading is reversed, yielding occurs in compressing at a value of 2σy. This is an approximation of the Bauschinger effect, a behavior seen by most metals.
