Abstract
This chapter presents simple computational tools for determining the stress intensity factors associated with small sub-mm cracks in realistic complex geometries under arbitrary flight loads. Attention is also focused on small initial cracks that first grow as a complex three-dimensional (3D) shape and then transition into a through-the-thickness flaws with an oblique (part) elliptical crack front. Unless otherwise stated these tools are used to perform the lifting and crack growth analyses performed in the various chapters in this book.
