Abstract - The influence of microplasticity effects on the
overall nonlinear behavior of unidirectional continuously reinforced
metal matrix composites is investigated by a finite element based
micromechanics approach using a periodically repeating unit cell.
The response under mechanical and thermal loading is modeled, the
influence of thermal residual stresses is considered, and shakedown
phenomena are studied.
The predictions from the numerical computations are compared with
experimental data on continuously reinforced boron-aluminum composites
and with analytical micromechanics results obtained from mean field
