Propagation elastic-plastic fields: asymptotic analysis of plane strain crack growth and restrictions on moving surfaces of strong discontinuity
The fracture of a ductile solid rarely occurs by the eruption of a stationary crack into catastrophic propagation; rather, a crack is often observed to extend slowly under increasing load or load-point displacement until the system becomes unstable. Consequently, understanding failure by fracture in such solids requires a knowledge of the stress and deformation fields which accompany a stably growing crack. Knowledge of these fields is also necessary to assess the effects of geometrical or material inhomogeneities on crack growth. Each chapter of this thesis constitutes a separate paper written for publication and contributes to the primary overall objective: elucidation of the stress and deformation fields near the tip of a quasi-statically advancing plane strain tensile crack in an elastic-ideally plastic solid.
