The extreme strength and toughness of the material is achieved by an interaction between the microstructure and fracture behaviour on the microlevel. In order to understand these mechanisms, detailed unit cells have been defined and used for the determination of the effective fracture properties. The results have been used for the implementation of an effective continuum damage mechanics model.Technology: general issuesbicsscfinite element simulationfracturesilicon nitridestructuretoughnessTechnology: general issuesWippler Johannesauth2006394BOOK9911115650303321Micromechanical finite element simulations of crack propagation in silicon nitride4792718UNINA
