This project has initiated and brought to completion several novel microscopic approaches to the prediction of material response to applied stress. In a series of several papers we worked out a systematic formulation of failure under load as a homogeneous nucleation process, simulating the process via mean- field, Monte Carlo and molecular dynamics methods, for both model and semi- empirical interatomic potentials. We also developed a biased-random-walk description of microcrack propagation which incorporated for the first time the effects of surface reconstruction. Finally we extended multiple scattering analyses of composite and concrete materials to the limit of high crack density, allowing for new nondestructive evaluations of this important class of materials.
