Effect of combined high-frequency and pulse-dynamic impact on adhesive-joint strength

Аннотация

The problem on exfoliation of a string on an elastic foundation under the application of external force is considered. The dependence of amplitude of the forced load, which causes the exfoliation of the string, on its frequency and application time is investigated. The exfoliation criterion under use is based on the concept of incubation time. It should be noted that, at certain values of the forced-vibration frequency, it is possible to decrease considerably the threshold-amplitude value.
