Conference paper


Damage and elasto-plastic analysis is of particular importance to metal matrix composites since the onset of damage and plastic yielding begins very early in the loading process as compared to the composite ultimate strength. Voyiadjis and Park [1,2] proposed the two different damage models for metal matrix composites. The first damage model accounts for all types of damages in the composites as a single damage variable, while the second damage model accounts separately for the damage of matrix and the fibers. This is coupled with the interfacial damage between the matrix and the fibers exclusively. These damage models are namely the “Overall Damage Approach”, and the “Local Damage Approach”, respectively. A finite element analysis is presented here for quantifying damage and predicting the failure loads of the center-cracked laminate plates.
