英文摘要
The principle objective of this work is to characterize analytically the stress and deformation fields accompanying crack growth in ductile single crystals and deformation fields at interfaces joining a ductile material to a brittle one. The analytical results will be checked with full-field numerical finite element solutions, and also with experiments that correspond to the analyses. The aim is to devise local descriptions, incorporating single crystal plasticity, as a function of general remote loadings.
