Abstract

There are numerous applications of rotating disc in the aerospace industry such as in gas turbines. There are many causes of disc failure. Among them, maximum tensile and bending stresses induced under the action of centrifugal forces are the main causes of disc failure. In this work, the evaluation of stresses in an E-glass epoxy material rotating solid disc is studied using finite element method. The FE model is developed by using ABAQUS software for analysis and the maximum principal stress is determined for different angular velocities. The analysis of stresses within the disc of constant thickness and density is based on the maximum principal stress criterion and its associated flow rule. It is observed that when increasing the angular velocity of the disc, the stress quadratically increasing. The result also shows that crack initiates at the center of the composite disc radially at a certain minimum speed.
