Thermal Elastic-plastic Stress Analysis of Steel Fiber Reinforced Aluminum Metal-matrix Composite Arches

A thermal elastic-plastic stress analysis is carried out on steel fiber reinforced aluminum metal-matrix composite arch under uniform temperature distribution. The arch is fixed at both ends. The composite material is assumed to be strain hardening linearly. First yielding temperature, thermal residual stresses and the distribution of these stresses under thermal loading are investigated by using finite element method (FEM). It is found that the orientation angle affects the yield point and the intensity of residual stresses significantly.
