摘要

In this study, an elastic plastic thermal stress analysis is carried out on steel fiber-reinforced aluminum metal matrix composite beams. Temperature is chosen to vary linearly. It is zero and T0 at the upper and lower surlhces, respectively. The beam is fixed by two rigid planes at the ends. The solution is performed at 0°, 30°, 45°, 60° and 90° orientation angles. The plastic region is expanded at the lower side of the beam. It is found that the intensity of the residual stress component of σ_x and the equivalent plastic strain are maximum at lower surface of the beam. The residual stress is found to be greatest for the 0° orientation angle. In addition. the intensity of the equivalent plastic strain is the greatest for the same angle.
