This paper deals with the fracture behaviour of layered ceramic composite with residual stresses. The main goal is to investigate the effect of residual stresses and material interfaces on crack propagation by more complex 3D finite element ...

Comparing R-curves for flat (straightened) and curved CT-specimens makes it apparent at the first sight that the R-curve obtained for curved CT-specimens has a smaller inclination than the R-curve determined for flat....
