Anotace
The proposed project is targeted to the research area being in focus due to gradually increasing number of applications of composite materials where the interface plays an important role. Main aim of the project is to determine parameters characterising fracture behaviour of multi-component materials mainly with the apparent interface. Detailed description of physical processes during the fracture will be used to achieve this aim. The influence of both local changes in the microstructure and fracture-mechanic parameters close to the interface on fracture micromechanisms and determined parameters will be exploited. It will be necessary to overcome the basic limiting factor which is the small thickness of layers or whole component given by the application potential of proposed materials especially on the field of optics and electronics. Further, there will be implemented developed material model of the interface into cohesive elements for numerical simulations using FEM. Progress reached in this globally attractive problematic will be utilized in development of new composite systems.
