摘要
结构性粘土具有明显的应变软化特性,迄今尚无合理的本构模型可用以描述其应力应变关系。笔者将原先建议的弹塑性损伤模型加以简化,提出了一个更实用的非线性损伤力学模型,制定了有关计算参数的测定方法,并对该模型的有限元算法作了初步的探讨。
The structured clay exhibits strain-softening property during shear,and until now no proper model is available to simulate its stress-strain behavior. In this paper instead of the earlier proposed elasto-plastic damage model a much simpler nonlinear damage model is suggested,and the procedure for its parameter determination is established.Finally the numerical technique for the application of this model in engineering practice is also discussed.
