Abstract

A method for the reconstruction of the configuration of cracks is suggested based on finding heat sources that model the interaction between cracks’ edges (such as friction and collapse) in solids exposed to external ultrasound. The input information for reconstruction is a stationary temperature field on a solid boundary. The functional of “nonreciprocity” was constructed; the study of this functional made it possible to convert the problem of determining a crack’s parameters into a few transcendental equations; explicit formulas were obtained for small cracks. The results of computational experiments on reconstruction of the parameters of a straight crack are considered.
