Abstract

An analytical approach is constructed to examine the limit stresses of multilayered fiber reinforced disk. Three different layer configurations are considered, which are decreasing, constant and increasing reinforcement from the inner to the outer radius of the disk. The multilayered disk is subjected to two boundary conditions, free-free and fixed-free. Stress fields are then obtained accordingly. In order to predict the limit stresses, Tsai-Wu criterion is implemented. Effects of different reinforcement configurations and various transverse Young's modulus estimations on the stresses are rigorously analyzed in the numerical examples. It has been mathematically observed that the disk with increasing reinforcement fails at higher angular velocities than other reinforcement types, and the selected Young's modulus affects the stresses in small to moderate scale.
