Abstract: Nonlinear Lamb waves including second harmonic and acoustic-radiation-induced quasi-static components (QSC) have a potential for accurately evaluating early-stage fatigue damage. Most previous studies focus on second-har ...

Abstract: Aging degradation is the main form of failure of rubber in service, leading to a decline in its physical and mechanical properties. This paper presents an efficient method for assessing the aging degradation of rubber using ...

Abstract: In this paper, a contactless nonlinear acoustic method is developed for the evaluation of stress states in anisotropic metallic plates by a combination of electromagnetic acoustic resonance (EMAR) technique and higher ...
