A novel singular finite element is presented to study cracked plates with arbitrary traction acting on crack surfaces. Firstly, the analytical solution around crack tips is determined using the symplectic dual approach. Subsequently, the solution is used to develop a novel singular finite element, w
Zero thickness crack tip interface elements for a crack normal to the interface between two materials are presented. The elements are shown to have the desired r\*-' (0 < I < 1) singularity in the stress field at the crack tip and are compatible with other singular elements. The stiffness matrices o
Two new boundary elements have been proposed for simulation of variable order singularities at the two ends of an element in two dimensions. The "rst can model the variable order strain singularity at both the ends of the element. The second element can do both the strain and traction singularities
