Abstract
We develop reduced basis approximations, rigorous a posteriori error bounds, and offline–online computational
procedures for the accurate, fast, and reliable prediction of stress intensity factors or strain energy
release rates for ‘Mode I’ linear elastic crack problems relevant to fracture mechanics. We demonstrate
the efficiency and rigor of our numerical method in several examples. Copyright q 2007 John Wiley &
