We propose a nondestructive method to characterize the quantitative bonding strength at a bonded solid-solid interface by a contact acoustic nonlinearity (CAN) microscope. The principle of the CAN microscope is briefly described. The vibration amplitude of the incident focusing wave at the bonded interface is calculated, the standard bonding strength with a complete bonding state is established by the tension test, and the CAN parameter is calibrated. The quantitative contour of bonding strength at the interface could be obtained. The experimental contours of two samples are also presented.

“…数。邓明晰 [74] 对复合结构黏接界面固化过程的非线性应力波因子进行了测量，结果表明，应力波因子与黏接层固化时间呈单调变化关系，且不同固化阶段应力波因子呈现不同特性，证明了应力波因子对于复合结构对界面黏接强度评价的可行性。Chen 等人 [75] 对施加不同时间拉伸的玻璃黏接界面进行了非线性超声检测，结果表明，非线性系数随界面拉伸时间的增加(即黏接质量的降低)而增加。在以上研究中，虽然黏接界面的黏接强度改变的具体方式不同，但得到的谐波非线性特征参数随黏接强度的变化规律一致，证明了谐波非线性技术对黏接强度评价的有效性。在黏接界面疲劳损伤方面，税国双等人 [76,77] 将铝合金黏接试件和镁合金黏接试件在高低…”

“…Besides, it can be described by high-order elastic constants or nonlinear ultrasonic coefficients [24]. The contact nonlinearity of solids mainly comes from the nonlinear stressstrain of cracks, interfaces, and contact surfaces [25,26], which reflects the local defect characteristics of materials. The existence of defects will lead to strong nonlinear distortion when ultrasonic interacts with it.…”

The dewetting damage of solid propellant under loading is a key factor affecting the constitutive properties of solid propellant, and it will weaken structural integrity of solid rocket motor charge. The quantitative characterization of its evolution process has always been a very active research field. In this study, a nonlinear ultrasonic (NLU) method is proposed to investigate and monitor in real‐time the nonlinear dynamic response of solid propellant. The NLU parameter, which can evolve dewetting damage, is expressed by some physical quantities such as the frequency peak, the propagation distance and so on, and is recorded at different strain in the tensile tests of the round rod solid propellant specimens. Then, the initial dewetting point, characteristic dewetting point and characteristic dewetting rate are defined to characterize the dewetting performance. The results show that NLU parameter changes continuously with the evolution of tensile process and increases sharply at the initial dewetting damage point. By analyzing the data, an empirical formula characterizing the variation law of NLU parameter with strain is proposed, which is well fitted to the experimental data under different strain rates. In addition, relevant numerical simulation is carried out, and the simulation results verify the feasibility of the NLU method.
