A method to obtain the two and three Weibull parameters from the statistical strength distribution of ceramics, when either surface flaws or volumetric flaws govern fracture, is outlined. The advantages of obtaining confidence in the parameter estimates are given realizing the flaw severity variations within a test population. The inadequacy of testing a very limited number of specimens to gather reliability data to assess service performance is discussed.

Effect Of Surface

Effect of surface flaw on ductile fracture behavior of non-aligned multiple flaws in plate is studied numerically using Gurson’s constitutive equation. Based on experiments, 2 parallel crack problems are simulated. In experiments and simulation crack coalescence, crack non coalescence and crack interaction was observed. In all cases, ductile fracture processes are obtained and results are compared with experimental ones. In this study, a new alignment rule for the prediction of maximum tensile load or rupture load for multiple cracked plates is compared with the simulation result.

Effect Of Surface

The first part of the paper discusses two problems in which the role of residual stresses may be treated using the procedures of fracture mechanics. One is the significant degradation of the tensile strength of glass due to the residual stresses produced by surface damage. The other is the effect of surface compressive stresses in inhibiting the detection of surface flaws. The second part of the paper discusses the inverse problem of using fracture mechanics solutions to measure residual stresses. This approach which has only been developed in the past decade leads to an experimental procedure which is easy to implement and is also more versatile than conventional methods.
