Sažetak
Computational plasticity finds one major application in metal forming simulations. In analysis of stationary forming processes, flow formulation with velocity field variables proves very convenient. Corresponding finite element algorithms very efficiently yield strain rate and stress distributions for complex viscoplastic constitutive equations. In this paper the classical flow formulation is extended to cases where the material constitution is a nonlinear function of both strain and strain rate. At finite element level this extension requires the determination of the trajectory of each numerical integration base point in the problem domain for the purpose of strain rate integration. Corresponding 2D finite element procedures have been developed and applied to idealized cold rolling process.
