On the kinetics of mobile Chernov–Lüders band fronts

The elastic-plastic transition occurs in materials having a sharp yield point simultaneously with the nucleation and propagation of Chernov–Lüders bands (CLBs). It is found that the time it takes for a given CLB to be nucleated differs by about an order of magnitude from its propagation rate. The CL...

Description
Summary:The elastic-plastic transition occurs in materials having a sharp yield point simultaneously with the nucleation and propagation of Chernov–Lüders bands (CLBs). It is found that the time it takes for a given CLB to be nucleated differs by about an order of magnitude from its propagation rate. The CLB fronts would travel in a concerted manner, so that their motion rates taken together at any time would make up a constant value. An increase in the deformation rate would bring about a nonlinear increase in the motion rates of CLB fronts.
