CRACK-PROPAGATION MODELING

In this paper, we review recent advances in mathematical and computer science techniques for modeling crack propagation in solids. The fract ure mechanics aspect of this problem is attacked by boundary integral equation methods, in particular the use of hypersingular integral equa tions for analyzing crack geometries. Key issues in the development of a software system capable of efficient crack propagation studies are also discussed. As an illustration of these techniques, calculations a nalyzing crack growth in a fuel door hinge on the Space Shuttle are pr esented.
