Influence of the T-stress on the crack bifurcation phenomenon in ceramic laminates
Original language description
The influence of the compressive residual stresses and layer thickness in ceramic laminates on the presence of the crack bifurcation phenomenon is numerically investigated in this contribution. Using the fracture criterion, based on the Finite Fracture Mechanics, the angle and type of crack propagation (single crack deflection/bifurcation) within the layers with large compressive stresses is investigated. Laminates with various thicknesses of the compressive layer and constant level of the compressive residual stresses are used for this purpose. In these cases, the level of the T-stress (in the vicinity of the crack tip) can play a role as a second parameter in the fracture criterion (next to the stress intensity factor) and as a consequence can this term influence the predicted crack propagation behaviour.
