Modified Multi-surface Kinematic Hardening Plasticity<br />
18<br />
K = K 0*D)<br />
The multi-surface kinematic hardening plasticity model (Mroz 1967) is<br />
modified for the fiber of the CZM-based macro-model to model cyclic<br />
loadings, softening and fracture<br />
n – line segments of constant tangent modulii: E 1, E 2, E 3,.., E n<br />
f 0, f 1, f 2 ,…, f n are hyper-surfaces with constant hardening modulii. All surfaces<br />
can translate in space without changing form and orientation<br />
