Microindentation Test Modelling in the Silicon Nitride Ceramics
Original language description
Silicon nitride based ceramics have received considerable attention during the last decades due to their very good room and high-temperature properties. Such ceramics are acknowledged as first choice for application of modern hybrid bearing applications.The influence of crack bridging by the elongated grains present in the microstructure on the strength and toughness is well known phenomenon from the side of experimental observation. The modelling of this complex microstructure by classical continuum mechanic approach usually do not provide sufficient results. The prediction of the crack propagation through interface elements based on the fracture mechanics approach and cohesive zone model was investigated. The cohesive models seem to be especially attractive for practical applications in case of silicon nitride based ceramics. The behaviour of such materials was studied by two types of elements using cohesive models. The former is the element for the classical continuum and the latte
