Transient mixed-mode elastodynamic crack growth along arbitrary smoothly varying paths is considered. Asymptotically, the crack tip stress field is square root singular with the angular variation of the singular term depending weakly on the instantaneous values of the crack tip speed and on the mode-I and mode-II stress intensity factors. However, for a material particle at a small distance awa...

In the past 53 years, many efforts have been contributed to develop and demonstrate properties of reinforced composite materials. The ever-increasing use materials through engineering structures needs proper analysis mechanical response these structures. proposed work, we an exact form Stress components Displacement a Griffith crack at interface Isotropic Orthotropic half-space bounded together...

1. Problem formulation. The processes governing the fracture of brittle solids are, at present, much less illuminated than those related to plastic deformations. The reason is that it is very difficult to observe the detailed fracture process directly. All one can determine is the load, which acted immediately before fracture started, and the path and nature of the fracture surface. Because dur...

Abstract Shrimali and Lopez-Pamies (2023, “The ‘Pure-Shear’ Fracture Test for Viscoelastic Elastomers Its Revelation on Griffth Fracture,” Extreme Mech. Lett., 58, p. 101944) have recently shown that the Griffith criticality condition governs crack growth in viscoelastic elastomers can be reduced to a fundamental form involves exclusively intrinsic fracture energy Gc of elastomer, and, so doing...

IF anyone had suggested a few years ago that I should present a paper on the clinical use of curare I would have been inclined to laugh, for to most of us curare has always been a fabulous poison vaguely connected with South American Indians and detective novels, useful in the physiological laboratory, but far removed from the realm of practical therapeutics. Nevertheless I have now to report i...

In the framework of level-set method we propose a topology optimization algorithm for linear elastic structures which can exhibit fractures. spirit Griffith theory, brittle fracture is modeled by Francfort-Marigo energy model, with its Ambrosio-Tortorelli regularization, also be viewed as gradient damage model. This quasi-static and irreversible model approximated using penalization to make it ...
