Location of pointlike acoustic emission sources in anisotropic plates

摘要: In this paper is described a method by which pointlike source of acoustic emission can be located in an anisotropic plate. The applicable for solid arbitrary symmetry as long the principal axes material are known priori. It shown that from time‐of‐flight differences particular features waveforms detected any pair sensors, set nonlinear transcendental equations formed coefficient each term related to differences, geometrical parameters array, and wave speeds quasiwaves propagating along source/receiver path. For waves planes, analytical expressions speed values used. Extension nonprincipal planes obtained computing eigenvalues Green–Christoffel tensor. Determination optimum location found minimizing Euclidean functional associated with th...
