Numerical modelling of fatigue damage in fiber reinforced composites and the proposal of experimental verification

Popis výsledku v původním jazyce

The use of composites in structures, which are subjected to cyclic loading cannot be avoided either. In this case, fatigue life of designed structures has to be evaluated. Fatigue damage in fiber composite is in comparison with metals more complicated and less described. The sign of fatigue damage in metals is a dominant fatigue crack which is regarded as dangerous, because it can cause final failure very fast. Fatigue damage in composites is cumulated in a whole volume of material and is characterizedby the development of more damage mechanisms. Due to these facts, the outer sign of fatigue damage is a significant stiffness reduction, which is good base for the development of phenomenological damage models. In this paper, the implementation of residual stiffness model to FE code and following testing is described. As a necessary step is regarded experimental verification of results. This issue is also discussed in this paper.
