WebThe semi-inverse solution (mainly by trial-and-error) for a crack in an infinite plate subjected to a remote stress σ is (2.24) Note the origin of the coordinate is at the center of the crack. By transforming the origin to the right-hand crack tip, i.e., z = a + re −iθ, all the stress components can be derived. 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.
