A constitutive model incorporating grain refinement strengthening on metallic alloys

Surface nano-crystallization techniques have been recently developed as one of the most effient ways to optimize materials’ structure, and therefore develop local global mechanical behavior increase strength without compromising ductility. In this work, we present a constitutive model incorporating grain refinement hardening simulate technique, specifically, surface attrition treatment. The computation is implemented using user-defined VUMAT subroutines. As an example its application, geometry with full coverage random impacts are employed. results show that has rather precise predictability size evolution during plastic deformation. readily embedded computational code material dynamics enables novel be promising tool study dynamic microstructures under
