Abstract: | The higher order asymptotic fields at the tip of a sharp V-notch in a power-hardening material for plane strain problem of
Mode I are derived. The order hierarchy in powers ofr for various hardening exponentsn and notch angles β is obtained. The angular distributions of stress for several cases are plotted. The self-similarity behavior
between the higher order terms is noticed. It is found that the terms with higher order can be neglected for the V-notch angle
β>45°.
