Abstract: This study proposes an litude-modulation vibro-acoustic (AMVA) technique to track the evolution of thermal damage in pristine graphene mortar. In the proposed litude-modulation technique, the pump wave is litude-modulated using three different methods: (1) the pure litude-modulated (PAM) method, (2) the suppressive litude-modulated (SAM) method and (3) the transmitted litude-modulated (TAM) method. The nonlinear parameters [Formula: see text], [Formula: see text] and [Formula: see text] corresponding to the PAM, SAM and TAM methods, respectively, are theoretically established and experimentally demonstrated that the nonlinear parameters associated with the material nonlinearity, and they can be used to quantitatively characterize different damage stages of thermal damage. Meanwhile, the resonant frequency (RF) and ultrasonic pulse velocity (UPV) tests are conducted. The linear measurements, dynamic elastic modulus [Formula: see text] obtained from RF test and ultrasonic pulse velocity [Formula: see text] collected by UPV test, are used to compare with the nonlinear parameters. The results show that the proposed AMVA technique is more sensitive and feasible to serve as the tool for thermal damage detection in cement-based material compared with the conventional RF and UPV techniques.

Abstract: Abstract. This paper proposes a new litude-modulation vibro-acoustic (AMVA) technique to detect thermal damage in pristine graphene (PRG) mortar materials. A new third-order solution for an litude-modulated low-frequency pump wave and a high-frequency probe wave in infinite isotropic material is presented. The solution includes higher-order sidebands generated by intrinsic and acquired nonlinearities. A nonlinear parameter is defined according to the third-order solution to assess the different levels of thermal damage. The experimental study demonstrates the sensitivity and feasibility of the AMVA technique by comparing the nonlinear parameter with the linear measurements of the ultrasonic pulse velocity (UPV) test. The results show that the proposed AMVA technique is a potential tool to detect and monitor thermal damage in cement-based structures.
