【 摘 要 】

A kinetic model of bonds destruction, interfacial adhesion strength and durability of interface junction is developed. It is assumed that a zone of weakened bonds exists at materials interface at an initial time instant. This weakened zone is considered as a crack-like defect filled with distributed spring-like bonds. Bonds mechanical properties are time-dependent under external loads. Bonds properties kinetics analysis is performed on the basis of Zhurkov's thermofluctuational approach of bonds destruction. The computational results those obtained on the basis of the developed numerical algorithm are presented.
