摘要

THE, plane stress steady crack growth in power-law hardening materials is significant in theoretical research and practical application, especially in the application in aeronautic and aerospace industries. But people have not yet found any analytic solutions to it because of the mathematical difficulty of the problem. Amazigo and Hutchinson studied the crack growth in linear hardening material for plane strain as well as plane stress by the numerical method, but the material model is quite differentfrom that of power-law hardening material. Later, numerical results for the problem by finite element method were published.
