Abstract
Deformation of solids is described as wave dynamics. Dynamics in all stages of deformation from the elastic sage through fracture are formulated comprehensively based on a fundamental physical principle known as local symmetry. The field equations derived from the present formalism lead to longitudinal, compression wave solutions in the elastic regime, decaying transverse wave solutions in the plastic regime, and solitary wave solutions in the transitional stage from the elastic to plastic regime. The decay characteristic in the plastic wave reflects the irreversibility of plastic deformation. The solitary wave can be interpreted as representing the dynamic shear band known as the Lüders band or the type A Portevin–Le Chatelier band.
