Elastoacoustic Effect in Rail Steel
Application ID: 4476
The elastoacoustic effect is a change in the speed of elastic waves that propagate in a structure undergoing static elastic deformations. The effect is used in many ultrasonic techniques for nondestructive testing of prestressed states within structures.
This example studies the elastoacoustic effect in steels typically used in railroad rails. The analysis is based on the Murnaghan hyperelastic material model, which is based on a 3rd order expansion of the elastic potential in terms of displacement gradients. This material model can be used to study various nonlinear effects in materials and structures, of which the elastoacoustic effect is an example.
