Abstract
The asymptotic stress field around a notch tip in an anisotropic power law material subject to antiplane shear is investigated. An anisotropic yield criterion and a flow rule are used to derive the anisotropic constitutive relation for such materials. Two problems of different notch surface boundary conditions are considered for remote antiplane shear loading. The stress exponents up to the first five terms of asymptotic solutions are determined through a hodograph transformation and numerical method. The effects of notch angle and material anisotropy on the stress exponents near the notch tip are discussed.
