Nondestructive Characterization of Quantitative Bonding Strength at a Bonded Solid-Solid Interface

         

摘要

@@ 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.
