dirty material

In order to test the validity of applying the Extended Finite Element Method(XFEM) in heterogeneous material with inclusions,the displacement field of a plate with multi-circular inclusions under uniaxial tension is simulated with both the XFEM method and the finite element method.

为了验证含夹杂非均质材料扩展有限元数值模拟的有效性,分别用扩展有限元法和传统有限元法模拟计算了一块含多个圆形夹杂的单轴受拉的板的位移场,并对模拟结果进行了对比分析。
