Over the past two years I've written up (or LaTex'd) a set of lecture notes on fracture mechanics. If you are interested you will find them at http://hdl.handle.net/1813/3075 in hyperlinked .pdf format. I've condensed a lot of material into these notes including LEFM, elastic-plastic fracture, experimental methods and some basics on computational fracture, so nothing is given in great detail. Of course a lot more could be done, but this served well for a one semester graduate class. The first reference in my notes is to Hutchinson's Course on Nonlinear Fracture Mechanics, the only useful text that we had to hang onto at Caltech when taking Rosakis's fracture course in the mid-80's.
