A Numerical Study Using Micromechanics Model for Metal Matrix Composites

A microcechanical analysis based on the single fiber model has studied in the standpoint of stress-strain hysteresis response. A comparative study of constraint and unconstraint effects ha been taken into account to investigate includes the stress grouping technique to evaluate the domain-based field quantities. Results indicated that the development of significant fiber stresses both for the tensile and compressive loading, due to the constraint effects, provides an important contribution to the composited strengthening
