Asymptotic solution of steady dynamic crack growth in a power-law elastic-plastic solid

摘要

Within the infinitesimal deformation and plastic incremental theory, an asymptotic solution of near-tip fields is presented in this paper for mode-I steady dynamic crack growth in a power-law incompressible elastic-plastic solid under plane strain conditions. This solution shows that the near-tip stresses and strains are fully continuous and bounded, and dependonly on one free parameter that must be determined from the far-field.
