Singular finite elements for the fracture analysis of V‐notched plate

Abstract

Abstract Special accurate and efficient hybrid elements were developed to account for notch‐tip singularities of type r γ , where γ can be complex. Proper normalization of the notch‐tip element size was used to minimize the oscillation of the assumed function around the boundaries of the element and to improve the accuracy of the solution. Examples of various notch angles and sizes are presented.
