Application of -integral on cracked structural beams
AbstractFor cracked engineering structural beams, a simple method to determine the stress intensity factors has been proposed based on a new concept of crack surface widening energy release rate. Unlike the classical crack extension energy release rate, the crack surface widening energy release rate can be expressed by the G∗-integral and elementary strength theory of materials for slender cracked three-dimensional structures. From present discussions, a series of exact solutions of stress intensity factors are derived for cracked structural T and I beams. The present method can also be applied to other cracked structural beams.
