| Abstract: | In this paper we consider the finite element treatment of the strain singularities of linear elastic fracture. We define two — new singular finite elements obtained from standard quadratic Serendipity and Lagrange elements, and we analyse their approximate strain forms. It is demonstrated that both elements can be applied in linear elastic fracture. |
