摘要
En 中文
Time integration in viscoplasticity is discussed from both engineering and mathematical points of view. A second-order integration scheme is presented and combined with an adaptive time stepping algorithm which utilizes local error estimates for the choice of time steps, and a closed-form expression for the consistent tangent operator is derived. The algorithm is applied to the viscoplastic model by Choi and Krempl. (C) 1999 Elsevier Science S.A. All rights reserved.
