Originální abstrakt
The paper is devoted to numerical modelling of R-curve behaviour in laminates with strong interfaces, in particular multilayers made of alumina (A) and zirconia (Z). Contrary to previous studies based upon the application of approximate weight function method originally developed for homogeneous specimens, a full field analysis by FE of a three-point bending test of a sandwich beam is attempted and compared with the results obtained by approximate weight function method. Also the crack penetration across the layer interfaces is discussed, particularly in the case of a weak singularity.
