    Probabilistic damage model for the crack propagation in Si3N4 ceramics

  • Original language description

    The microstructural constitution of silicon nitride possesses the ability to enhance fracture propert ies by changing the grain shape parameters and change the glassy phase composition. The composition of the glassy phase plays significant role in the grain formation. Usually, the elongated beta silicon nitride grains homogeneously distributed within the m icrostructure formed from equi - axed grains creates significant obstacle for propagating crack. There are few mechanisms that acts during the fracture process and led to enhanced fracture resistance of the material. First one is the crack bridging, where op ening of existing crack is constrained by the elongated grain in elastic regime. The second is the grain trans - granular fracture where the elastically loaded bridging grain is fractured and this grain fracture consumes some portion of accumulated energy st ored in the system. The third mechanism can be seen when the crack is somehow forced to change its direction and use delami
