Abstract

The second part of the paper is devoted to the implementation of the presented algorithm. To validate the proposed general algorithm several problems are computed. One is the fracture analysis of 4-layered symmetrical laminate with respect to stacking angles. The other is the prediction of the most probable interface and the critical stresses for the onset of delaminations. The results of multilevel, multimodel and multivariant analysis of 3D delamination problems with detailed microstructure in the crack tip zone are also presented.
