Finite Elements for Determination of Crack-Tip Elastic Stress Intensity Factors.

Abstract

In the report on finite elements for determination of crack-tip elastic stress intensity factors, a new type of finite element is introduced which embodies the inverse square root singularity present near a crack in an elastic medium. Using this element near the tip in two typical cracked configurations, stress intensity factors within five percent of accepted values were obtained with meshes having as few as 250 degrees of freedom.
