説明
The inverse method applied successfully to several basic structures is extended to estimate dynamic stress intensity-time history for one point bend specimens. The response functions of the specimens are estimated by de-convolving the specimen response measured near the crack tip with the measured impact force. Two methods of deconvolution were used, e. g., a simple statistical method and a CG-FFT iteration method. The ill-posed nature of the deconvolution is removed successfully by the CG-FFT method and then the excellent estimation is obtained.
