Metal/ceramic multilayer (MCM) nanocomposites exhibit promising mechanical properties, i.e. high strength and high ductility, which vary with the individual layer thicknesses. Studying the mechanical behavior of MCM’s when the structure is composed of a great number of nano layers requires the implementation of some relations that can predict the material behavior correctly. Hence, molecular dynamics simulations results on MCM’s systems were used to develop a continuum model within the framework of viscoplasticity theory. The mechanical behavior of MCM nanocomposites is studied for different layer thicknesses depending on the controlling deformation mechanisms including Hall-Petch, confined layer slip, and dislocation nucleation mechanisms.
