Original Abstract

The aim of the work is to investigate theoretically the transition between two basic mechanisms of toughening of brittle solids through the inclusion of ductile phase. The first mechanism of thoughening is accomplished extrinsically, i.e. through the development of crack-tip shielding from crack deflection and/or crack bridging by intact ductile particles in the crack wake. The stress-crack opening displacement relationship relies upon the constant volume plastic flow of the particles according to the model used in previous works. According to the second mechanism the crack is arrested at the ductile phase such that it must renucleate on the other side. The resultant crack trapping acts to toughen the material intrinsically.
