Evaluation of damage accumulation for ductile materials
Original language description
The damage accumulation is one of the issues of ductile fracture modelling. One of the potential methods for assessing the damage evolution may be the tracking of the change in Young’s modulus. This contribution presents three measuring approaches to following the decrease of Young’s modulus, which is related to the damage progression. Simple loading-unloading technique was compared to the two approaches using the ultrasound. In one approach utilizing the ultrasound, the test was stopped for measuring the wave velocity, while no interruption was present during the other approach. The technique employing the ultrasound without stopping yielded rather scattered results with no trend observable. Nevertheless, the loading-unloading method resulted in greater degradation of Young’s modulus than in the techniques which applied the ultrasound.
