Nondestructive Testing in Mechanical Engineering by Wave Inversion
In this paper, we present a new approach for the nondestructive testing for deffecting cracks in materials by using wave parameter inversion that includes mechanical and effectromagnetic wave parameter. We use singularity properties pulse function and convolution to find the Frechet derivative of the nonlinear response operator on the wave velocity. The Frechet derivative operator is weak ill posed integral geometry form in the manifolds. We use Newton method to solve the nonlinear equation for wave velocity inversion. Using the wave velocity inversion, we can deffect the crack and properties anomalous in the materials.
