摘　　要：将有限条带法 (FSM)中两端固定条和有限单元法 (FEM)中矩形单元的位移函数相迭加 ,运用混合条元法来求解平面弹性力学问题 .结果表明 ,该种混合条元能有效地减小计算工作量 ,具有适用性强、收敛性好等特点 .By combining the displacement function of two_end fastened strip in finite strip method (FSM) with that of rectangular element in finite element method (FEM), the compound finite strip_element method is used to solve plane problems with mechanics of elasticity. It shows that this type of compound finite strip_element can lighten the computing workload , and it is of great applicability and good convergence.
