ln the present paper a summarizing survey is given on crack propagation in AIZnMgCuO.5 under both cyclic and monotonic loads. Details of the investigation are already published elsewhere. By systematic arrangement of the results it can be shown that micromechanisms and macroscopic crack propagation

The effect of two singularity fields: the HRR solution and a modified form of Rice's solution for the anti-plane shear, on the fatigue crack propagation are investigated. A unified crack growth rate equation is derived involving mechanical, cyclic, fatigue properties as well as a length parameter as
AbstractΓThe mechanisms of cyclic fatigue-crack propagation in a grain-bridging ceramic, namely an in situ toughened, monolithic silicon carbide, is examined. The primary goal is to directly quantify the bridging stresses as a function of cyclic loading. To investigate the eect of the number of load
