CONSTITUTIVE BEHAVIOR OF THE COMPOSITES WITH BOTH MATRIX CREEP AND SLIGHT INTERFACE CREEP

Under certain temperature and stresses metal matrix composites can exhibit pronounced creep deformation When the interfaces of composite are imperfect and viscoelastic, they also considerably contribute to the global creep behavior Based on the Mori Tanaka method for composites with imperfect interfaces, this paper studies the constitutive behavior of the composites with both matrix creep and slight interface creep The effects of various microstructural parameters are carefully examined
