Modeling of High-Temperature Plastic Deformation of Layered Composites Based on Alloys with L12 Superstructure

Abstract

Method of mathematical modeling is used to investigate macrolocalization of plastic deformation and, in particular, the possibility of forming superlocalization bands in layered composites exposed to hightemperature uniaxial deformation. Modeling is based on a combination of continuum mechanics methods and dislocation kinetics of alloys with L1₂ superstructure. Numerical modeling is performed by the finite elements method.
