Numerical simulation of contact interaction between a tool and a plastically deformable body through a viscous-plastic material interlayer

摘要

A finite-element model of isothermal settlement of a three-layered workpiece with differing rheological properties of the central and surface layers serves to predict the rheological parameters of the viscoplastic surface layer (the interlayer) reducing the force of deformation, saving the resource of plasticity (the damage extent) and malting hot deformation more regular.
