Abstract
Abstract In this paper, we use the notched anisotropic plates at infinity under uniaxial tensile stress, and we use the finite element method to analyze the relationship between stress concentration and the matrix damage zone growth according to different proportions of plate thickness and the opening radius. First, we compare the result of “ANSYS” simulation under the assumed two-dimensional condition with the literature in order to validate simulation value. Second, we consider the relationship between isotropic stress concentration plate and plastic zone growth under the condition of three-dimensional elastoplastic. Finally, we analyze the relationship between stress concentration and the substrate damage zone, according to different angles between the force direction and fiber orientation of the anisotropic fiber reinforced plate. We found that in isotropic materials the stress concentration factor has a significant influences on plastic zone growth. In anisotropy material, the angle between force direction and fiber orientation are closely related to substrate damage zone growth. Keywords: anisotropy, stress concentration, elastoplastic
