Weight Function Method for Crack in Orthotropic Materials,ss intensity factors (SIF), crack opening displacements (COD) and weight functions available for cracked composite plates. In this chapter, the Wu-Carlsson weight function method (WFM) for isotropic material is extended to crack analysis in orthotropic material. Explicit weight function for an edge

Weight Function Method for Collinear Cracks and Its Application to Multiple Site Damage,rived and exact weight functions (WF) for two and three collinear cracks are given this chapter. The WFM is then used to determine the stress intensity factors (SIFs), crack opening displacement (COD) and plastic zones of two and three collinear cracks in unstiffened and stiffened plates. These resu

Analysis of Cracks in Thermal and Residual Stress Fields Using Weight Function Method,al and residual stress fields that are characterized by strong variations and steep gradients due to their self-equilibrating nature. The validity of superposition principle for SIFs of cracks subjected to thermal/residual stresses is proved, and several important aspects in crack problem analysis i

Computation of Crack Opening Displacements and Crack Opening Areas Using Analytical Weight Function. Analytical COD-expressions are derived for three types of basic crack line stresses: distributed stress over the entire crack, a segment of uniform pressure and a pair of point forces acting at arbitrary location of the crack. Calculation methods for crack opening displacement at crack mouth and a
