Web8thEuropeanLS-DynaUser Conference,Strassbourg23.-24.05.2011,SebastianMönnich 3 Motivation WebA theory of plasticity is developed for a material which is initially isotropic and satisfies the maximum shear stress initial yield condition. It is shown that the most general piecewise linear theory depends upon 5 material constants. These include the initial yield stress, the rate of hardening, and three constants which describe the effect of hardening upon the …
