Abstract

AS EXTENSION OF THE PREVIOUS TWO-SURFACE MODEL IN PLASTICITY, A TWO-SURFACE MODEL FOR VISCOPLASTICITY IS PRESENTED HEREIN. IN ORDER TO VALIDATE AND INVESTIGATE THE PERFORMANCE OF THE PROPOSED MODEL, SEVERAL NUMERICAL SIMULATIONS ARE UNDERTAKEN ESPECIALLY FOR STRUCTURAL STEEL UNDER MONOTONIC AND CYCLIC LOADING CASES, WHERE EXPERIMENTAL RESULTS AND NUMERICAL RESULTS FROM THE RATE DEPENDENT KINEMATIC HARDENING MODEL ARE ALSO PROVIDED FOR THE REFERENCE. FOR ALL THE CASES STUDIED, THE PROPOSED MODEL CAN APPROPRIATELY ACCOUNT FOR THE RATE-EFFECTS IN BOTH MAXIMUM STRESS AND HYSTERETIC SHAPES.
