Abstract
A "stick slip" fracture model based on an "inertia-dependent" modified equation of motion for the crack tip and a "non-monotonic" fracture toughness velocity curve is presented and analyzed with the aid of techniques commonly used in non-linear dynamics. As a result of an analysis for constant applied extension rate fracture tests, macroscopic stick-slip fracture oscillations (with crack jump increments larger than the length of the "fracture process zone") are shown to be self-oscillations and described by a limit cycle in the energy release rate-crack tip velocity plane. Numerical results are presented and compared with experimental stick slip fracture observations. © 1995 Elsevier Science Ltd.
