Micromechanical Modelling of SiC reinforced in 8090Al-Li alloy Metal Matrix Composite
Abstract
In the present study, the stress transfer efficiency between matrix and particulate and deformation has been carried out for RVE of a particulate reinforced metal matrix composites (MMCs) by developing a micromechanical model. It is observed that the stress transfer efficiency decreases with increase in particle volume fraction. The maximum and minimum stresses are induced in the direction and 90° to the direction of applied load respectively. The particulate reinforced metal matrix composite is the brittle particle (silicon carbide) reinforced in ductile matrix material of 8090Aluminium-Lithium alloy material.
