A Hermitian Type Triangular Element only with Corner Nodes and its Application to XFEM
A new triangular element of Hermitian type, i.e., the degrees of freedom includes differentiation of value as well as value itself, is proposed and XFEM formulation is demonstrated. Some numerical examples are also shown.
