WebJun 3, 2015 · The effects of various dynamical test loads on the crack identification are investigated. For a time-harmonic excitation with a single frequency and a short-duration signal measured along part of the external boundary, the crack is detected through the solution of an inverse time-dependent problem. WebOct 30, 2024 · The inclined crack has the maximum fatigue life, the side crack has the minimum life, and the middle crack has an in-between life. (4) These three test configurations provide three different mixed mode behaviors of cracks. As middle cracks occurred, there were two initial cracking points in the structure with the stress-absorption …
