Application of Nonlinear Ultrasonic Technique to Characterize the Damage Evolution in Structural Steel after Tensile Deformation

CODEN: JTEVAB

Abstract

A nonlinear ultrasonic technique has been used to characterize damage evolution in structural steel subjected to tensile loading. The results show that the nonlinear parameter β increases monotonously with increasing tensile strain within its tensile strength. Compared with the original specimen, the nonlinear parameter rose by nearly 3.37 times when stretched to its tensile strength. This result indicates that the nonlinear ultrasonic technique is able to characterize the material damage at the early stages, which can become an effective means for improving the integrity and safety of the structural component.
