Strain localisation trouble

Hi All, I developed a non-ordinary PD solver for thermo-elastic body. Unfortunately, when I try to calculate crack propagation, instead of strain localization and crack prop. the cracking "bonds" strats to spread and the calculation colapse. Have you got similar experiences? Any idea what can be the reason? How to solve? Thank you for your any suggestion... -- G. Ladányi
