Wirksame Wissenschaft und Forschungression for the crack tip energy flux in terms of near tip mechanical fields which is valid for general material response is derived. It is then demonstrated that certain useful energy integrals may be extracted from the general result by invoking the appropriate characterization of material respons

,Einleitung ‒ Von innen nach außen,mesh” finite-element procedures are examined. Simple procedures, using a moving mesh of conventional isoparametric elements in conjunction with certain path-independent integrals for the evaluation of stress-intensity factors for a dynamically propagating crack are presented.

Carla Küffner,Christine Pichlern that these dynamic effects can be significant: For cracks at arrest the stress condition is still dynamic and not static although the crack velocity has become zero. Dynamic effects become small only for small crack velocities or small crack jumps or for specially designed specimens. It is shown t

The importance of integrating experimental and computational work in this

Some basic problems in stress wave dominated fracture,ng the assumptions underlying an idealized model of brittle, dynamic fracture we review experimentally observed deviations from such idealized behavior. Such deviations are ascribed to the development of numerous microcracks in the crack tip region. These microcracks determine the crack initiation p
