Estimation of the Elasticity Coefficients of a Homogeneous Anisotropic Material Based on Echo Signals Measured by One or Two Ultrasonic Antenna Arrays
Source abstract
Abstract
Abstract High-strength pipes of class K60, which have anisotropic properties, are used for the construction of pipelines. When conducting ultrasonic inspection of welded joints using digital aperture focusing (DFA), it is usually assumed that sound propagates in a homogeneous isotropic medium. The DFA method can be modified to obtain images of reflectors in a homogeneous anisotropic medium, but for this one needs to know the type of symmetry and elasticity coefficients. Obtaining this information is an urgent problem. The article discusses two algorithms for estimating elasticity coefficients based on echo signals measured by one or two ultrasonic antenna arrays.
