Description

Acoustoelasticity is a method for evaluating the state of stress in a material by making measurements of the relative velocity change of an ultrasonic wave propagating through the stressed medium. The physical basis of this technique is the slight nonlinearity found in the stress-strain curve in the elastic region. This nonlinearity is often characterized by the introduction of two types of elastic constants: second-order elastic constants (SOEC) which describe the material behavior in the absence of stress, and third-order elastic constants (TOEC) which describe the nonlinearity.
