The ball on three balls test for strength testing of brittle discs: stress distribution in the disc
Biaxial strength testing of brittle materials is claimed to have some benefits compared to uniaxial testing, e.g. the much simpler specimen preparation, the avoiding of tensile loaded edges, the… Expand
Fracture statistics of ceramics – Weibull statistics and deviations from Weibull statistics
Abstract It is claimed in almost every experimental work on ceramics that the strength is Weibull distributed. The literature demonstrates that this is not valid in any case, but it is up to now the… Expand

The fit of fracture strength data of brittle materials (Si(3)N(4), SiC, and ZnO) to the Weibull and normal distributions is compared in terms of the Akaike information criterion. For Si(3)N(4), the… Expand
The ball on three balls test for strength testing of brittle discs: Part II: analysis of possible errors in the strength determination
Biaxial strength testing of brittle materials using the ball on three balls test (B3B test) is a useful tool for direct strength testing of disc specimens offering some advantages compared with the… Expand
The ball on three balls test—Strength and failure analysis of different materials
Abstract The ball on three balls (B3B) test is a new method for biaxial strength testing of brittle materials. A detailed analysis of the stress field in the specimens and of possible measuring… Expand
A method for fracture toughness testing of ceramics ready for standardisation.
Fracture of Ceramics
The paper reviews the current state of art of the fracture of brittle ceramic materials. Typical loading situations (thermal shock, contact damage) are analysed and the resulting fracture modes are… Expand
Influence of surface defects on the biaxial strength of a silicon nitride ceramic – Increase of strength by crack healing
Abstract Failure of brittle materials starts in general from defects which exist in the volume or on the surface of the specimens. Surface flaws, which are more dangerous than volume flaws, can be… Expand
Prediction of the fracture toughness of a ceramic multilayer composite – Modeling and experiments
Abstract A procedure to predict the fracture toughness of a ceramic multilayer composite made of different phases is presented. The procedure requires experiments to measure the intrinsic fracture… Expand
Mechanical characterisation of miniaturised direct inkjet printed 3Y-TZP specimens for microelectronic applications
Direct inkjet printing (DIP) allows the production of small ceramic specimens with special geometries starting from high solids content suspensions. In this work, thin (300m thickness) 3Y-TZP… Expand
