О модели Дагдейла для трещины на границе раздела различных сред

Abstract

Calculation of the initial plastic zone at the end of the crack on the interface of different media is presented. The plastic zone is modeled by the Leonov-Panasyuk-Dugdail plastic strip, emerging from the end of the crack and also located on the interface of different media. An exact acolution of the corresponding plane static problem of the theory of elasticity is constructed by the Wiener-Hopf method.
