Using rate-independent evolutions as a framework for elastoplasticity, an a posteriori bound for the error introduced by time stepping is established. A time adaptive algorithm is devised and tested in comparison to a method with constant time steps. Experiments show that a significant error reduction can be obtained using variable time steps.

弹性塑性的自适应时间步长

使用与速率无关的演化作为弹塑性的框架，建立了由时间步长引入的误差的后验约束。与具有恒定时间步长的方法相比，设计并测试了时间自适应算法。实验表明，使用可变的时间步长可以显着减少错误。
