Abstract

Damage tolerance is increasingly important in the composite structural design community. However, there are very limited solutions of closed-form stress 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 crack in an orthotropic strip is provided. Through extensive verifications against results from finite element analyses (FEAs) and existing literature data, the present WFM is demonstrated to be highly accurate, efficient and versatile for calculating SIFs and CODs for edge cracks in orthotropic materials.
