APPLICATION OF MESH-LESS METHOD IN ANALYSIS OF ELASTIC-PLASTIC STABILITY OF AN EDGE SLOPE

摘要: 将无单元伽辽金法(EFGM) 推广到求解弹—— 黏塑性问题, 自行编制了相应的计算程序, 并应用于土质边坡的弹塑性稳定分析. 通过无单元伽辽金法计算结果与有限元法的计算结果的对比分析, 可以发现用黏弹塑性问题的无单元伽辽金法计算程序去求解弹塑性问题是方便可行的, 本文编制的计算程序稳定性好, 收敛速度快.

Abstract: The element-free Galerkin method(EFGM) is applied to solve the elastic-viscoplastic problems in this paper. The corresponding computational program is written and applied to the elastic-plastic stability analysis of the edge slope. The comparisons and analyses of the numerical results of EFGM and FEM show that EFGM for elastic-viscoplastic problems is effective with good computational stability and convergence.
