Ultrasonic Detection of Nonlinear Mechanical Behavior of Adhesive Bonds

Measurement of Adhesion Strength of Bonds Using Nonlinear Acoustics

“…For a completely disbanded interface Zo2 = 0, hence r = -1 doubling the particle velocity at the interface and the displacement However, the strain So at the interface will be zero. The mechanical displacement aCt) of the interface due to the incident ultrasonic wave with frequency COt, amplitude Uo and the wave number k depends on the restoring force at the interface [12]. aCt) can be written as:…”
