✦ Synopsis

Abstrac-An analytical elastoplastic solution for mode III cracking is obtained for a finite-width plastic zone model. This model recovers as special cases the small scale yielding elastic/perfectlyplastic solution proposed by Hult and McClintock, and a plastic strip model for mode III proposed by Cherepanov, which is analogous in shape to the Dugdale plastic strip model of mode I. The model presented here represents a transitional phase of mode III cracking where the elastio-plastic boundary assumes an elliptical form. The stress, strain and displacement fields are presented for both the elastic and plastic regions. A discussion of this solution as it applies to material phenomenology is also given.

The Dugdale [i] and Bilby, Cottrell and Swinden [2] model of an elastic/plastic crack is well known. In their model (hereafter referred to as DBCS model) the yielding is assumed to be confined to an infinitesimally narrow band. In practice, however, there is always some lateral spread of yielding

The problem of an orthotropic strip containing two collinear cracks normal to the strip boundaries is considered. The Fourier series method is used to reduce the associated boundary value problem to triple series equations, then to a singular integral equation, which can be solved analytically. Unde

Oscillations observed in the load-displacement response of brittle interfaces modeled by cohesive zone elements in a quasi-static finite element framework are artifacts of the discretization. The typical limit points in this oscillatory path can be traced by application of path-following techniques,
