Material degradation is usually preceded by some kind of nonlinear mechanical behavior before significant plastic deformation or material damage occurs. When an ultrasonic wave propagates through the material at this stage, a strong nonlinear effect will be generated and thus higher harmonics will be produced due to the nonlinear elastic properties of that material. In this paper, advances in experimental and theoretical studies of nondestructive test and evaluation (NDT and NDE) of material degradation under...

Material degradation is usually preceded by some kind of nonlinear mechanical behavior before significant plastic deformation or material damage occurs. When an ultrasonic wave propagates through the material at this stage, a strong nonlinear effect will be generated and thus higher harmonics will be produced due to the nonlinear elastic properties of that material. In this paper, advances in experimental and theoretical studies of nondestructive test and evaluation (NDT and NDE) of material degradation under fatigue, tension and creep loads using nonlinear ultrasonic waves were reviewed, including advances in experimental and theoretical studies of NDT and NDE of bond strength and mechanical degradation of adhesive joints. Also, further studies in the field of NDT and NDE using nonlinear ultrasound were suggested.
