Abstract
In order to investigate whether the two fatigue processes, crack initiation and propagation, can be combined, and the change of local notch-root strain. And its history are measured as well as the change of local crack-tip strain and the local strain history of a fatigued element ahead of the propagating crack-tip up to failure in a polycarbonate subjected to low-cycle fatigue tests by the fine grid method. As a result, the existence of a unified local strain field where the two fatigue processes can be substantially combined is experimentally confirmed. Therefore, the local crack-tip strain may be examined by a simpler, one-parameter approach for fatigue life estimation.
