Original abstract
This contribution deals with 3D analysis of three point bending specimen with chevron notch made of fibre reinforced composites. Fibres bridge the crack initiated at the chevron notch. On macroscale the specimen is modeled as an elastic homogenous and transversally isotropic material with average elastic constant. At the nodes on face of crack there are prescribed tensile forces which are given by function of displacement of node times the area of face of element in plane of crack.

Příspěvek se zabývá 3D analýzou 3- bodového ohybu vzorku s chevron vrubem, přičemž materiálem vzorku je křehký kompozit zpevněný vlákny. Vlákna přemosťují trhlinu iniciovanou v chevron vrubu. Na makroúrovni se vzorek modeluje jako homogenní, příčně isotropní těleso se zprůměrovanými elastickými konstantami. Účinek přemostění je modelován pomocí závislosti mezi msotícím napětím a rozevřením trhliny.
