The influence of imperfect interfaces on the overall mechanical response of metal-matrix composites

摘要

A systematic study of the overall mechanical response of strongly or weakly bonded periodic composites was performed. Results have been recovered in the extreme conditions of perfect adhesion and pure friction. The aim of the investigation is to evaluate the sensibility of the overall material behavior to the interface characteristics and to evidence the load transfer mechanisms between the matrix and the inclusions. The problem is particularly relevant for metal-ceramic composites, due to low chemical affinity and difficult production processes that can prevent the desirable coupling between the components.
