摘要
Drucker- Prager模型广泛应用于混凝土、岩石等材料 ,采用空间 8节点等参单元对其进行增量迭代计算 ,每增量步内 Newton- Raphson法迭代 2次 ,4阶高斯积分 。
Drucker Prager yield criterion is widely applied to materials such as concrete,rock,etc.Spatial eight joint element is used to perform incremental iterative computation to analyze these materials.The nonlinear equations are solved by Newton Raphson incremental iterative procedure,iterating two times for every increment step,and using four order Gauss quadrature.The results of computation examples coincide with the theoretic analysis precisely.
