Ultrasonic techniques are widely employed for nondestructive testing. However, residual stresses in materials, resulting from service conditions or from manufacturing processes such as rolling, drawing, or welding, usually cause significant nonlinear effects in. stress wave propagation. The elastic wave speeds can be changed by stresses in a solid; this phenomenon is called the acoustoelastic effect.
