단섬유 금속복합체에서의 소성역 전개과정 및 바우신저 효과에 관한 연구 = A Study on the Evolution of Local Plasticity and the Bauschinger Effects in Short Fiber Reinforced Metal Matrix Composites

다국어 초록 (Multilingual Abstract)

A continuum analysis of the evolution of plasticity and Bauschinger effect in a short fiber reinforced metal matrix composite, based on the FEM solution for a single fiber model has been performed to investigate the strengthening behavior. The evolution of matrix field quantities during one cycle of fully reversed loading have been examined in detail. The results indicate that the role of constrained matrix flow in generating contribution to the development of the Bauschinger effect in the metal matrix composite. Therefore, even when the plastic flow of the matrix material follows on isotropic hardening behavior, the Bauschinger effect is predicted for the composite material.
