Modelling of Crack Bifurcation in Laminar Ceramics with Large Compressive Stress
as a barrier to crack propagation. The goal of the contribution is to model the mechanism of crack bifurcation in laminar ceramics with large compressive stress which still have. Ceramic laminates designed with strong inte...

Assessment of crack-related problems in layered ceramics using the finite fracture mechanics and coupled stress-energy criterion
(such as the edge cracking, crack arrest by the compressive layer or crack deflection/bifurcation) and proposes an effective approach to describe the initiation and/or propagation of cracks in such materi...

Analysis of the causes of damage of the header and nozzles
and the nozzles of the boiler superheater. It was found that both types of cracks, either fatigue, which was caused by cyclic changes in wall temperature. The bifurcation of some cracks in the header wall then indicates th...

Layered ceramics with internal compressive stresses to improve strength and toughness
The aim of this work is to provide design guidelines to optimise strength and toughness of layered ceramics using compressive residual stresses in the internal layers. Bio-inspired layered ceramics have been proposed as an alternative choice to conve...
