Abstract: The aim of the present study is to compute the macro- and microstress concentration in a reinforced biomaterial composite plate with a circular hole with respect to the volume ratio of the component materials in the composite. The contour of the circular hole and its dependency on the structure of a plate were calculated in order to study the behaviors of macro- and microstresses. In this paper, the stress around a circular hole was calculated for an orthotropic unidirectionally fiber-reinforced plate with respect to the volume ratio of the component materials in the composite. Stress distribution using a theoretical method and the finite elements method was calculated. The boundary conditions applied on the contour of a circular hole are uniform normal pressure. In this present study, we use a new numerical method of determining microstresses for composite plates with a circular hole, on the boundary of which there is a uniform normal pressure. The results demonstrate the macro- and microstresses calculated for two different structures and the behavior of an orthotropic plate with a circular hole. The ANSYS package and the finite-element representative plate model were used in this study.

Keywords: composite, unidirectional fibers, numerical method, boundary conditions, stress concentration.
