✦ Synopsis

Abatrati-A rigorous theory of non-linear fracture mechanics consistent with the basic laws of thermodynamics is proposed. It is shown that the local balance equation(s) can be derived from the postulated global balance equation using a generalized Reynolds transport equation appropriate to a body containing a growing crack. The necessary conditions to be fulfilled on the newly created fracture surfaces are derived. Within the framework of local theory the governing equations are applicable to crack problems in materials with internal variables or fading memory and to geometrically and/or physically non-linear problems. As a special case, the governing equations for infinitesimal thermoviscoelastic fracture mechanics are given.
