在这项工作中,我们提出,分析和实现的残余后验误差估计的弹性系统在两个空间维度近似的扩展有限元法(XFEM)。XFEM允许使用非裂纹域的网格进行多裂纹域的有限元计算,通过添加Heaviside型和奇异函数的补充基函数,以分别考虑裂纹的几何形状和裂纹尖端的奇异性。
In this work we propose, analyse and implement a residual a posteriori error estimator for the elasticity system in two space dimensions approximated by the eXtended Finite Element Method (XFEM). The XFEM allows to perform finite element computations on multi-cracked domains using meshes of the non-cracked domain by adding supplementary basis functions of Heaviside type and singular functions in order to take into account the crack geometry and the singularity at the crack tip respectively.
