Abstract
This report is a review of the subject of fracture mechanics focusing mainly on its application on stiffened sheet structures. It is written for readers who have some basic knowledge of fracture mechanics in a general sense but are interested in learning more on this specific and complex aspect of the subject. This report has six chatpers. Chapter one is an introduction that focuses onthe application of stiffened sheet structures. Chapter two reviews the fracture mechanics concepts of strain energy release rate, stress intensity factor, crack resistance and residual strength. Chapter three presents the general theories behind dynamic fracture mechanics and the crack arrest process. Chapter four applies the concepts and theories from Chapter two and three to stiffened sheet structures. Factors that can be used in designing these structures and various parameters that affect their performance are described in this chapter. The graphical representation of the crack arrest process in these structures are also presented in this chapter. Chapter five discusses several methods for analyzing and modeling stiffened sheet structures. In particular the analytical method, the finite element method, the boundary element method, and the finite difference method are presented. Results from several investigators demonstrate the effectiveness of each of these methods. Chapter six contains the concluding remarks on this report.
