| Summary: | ABSTRACT
A method is developed for the detection of the crack propagation in a plate with single edge crack. It extends previous work The plate was subjected to various combinations of stress levels (SL) and stress ratios (R). Two accelerometers were used to measure the longitudinal displacement amplitude at the plate's crack region. Data acquisition was done by measuring the longitudinal displacement amplitude at specific crack length, as well as by counting the cycles. The accuracy of the results is further assessed by comparison with results from the previous work. It is shown that the present work can yield very accurate results. In order to validate the method used in the present study, the results of this method is compared with results of numerical finite element calculations, and the agreement is quite satisfactory.
