Quasi-Static Crack Propagation by Griffith’s Criterion
We consider the propagation of a crack in a brittle material along a prescribed crack path and define a quasi-static evolution by means of stationary points of the free energy. We show that this evolution satisfies Griffith’s criterion in a suitable form which takes into account both stable and unstable propagation, as well as an energy balance formula which accounts for dissipation in the unst...
متن کاملA Notched Disk Crack Propagation Test for Asphalt Concrete
Cracking is a major distress in asphalt pavement which can lead to premature pavement failures and can cost agencies millions of dollars in maintenance and rehabilitation costs. Even with modern advances in pavement engineering, attempts to quantify and model cracking in asphalt pavements have proved extremely challenging; this is due to the visco-elastic behavior of asphalt concrete and the co...

متن کاملEffect of Crack Blunting on Subsequent Crack Propagation
Theories of toughness of materials depend on an understanding of the characteristic instabilities of the crack tip, and their possible interactions. In this paper we examine the effect of dislocation emission on subsequent cleavage of a crack and on further dislocation emission. The work is an extension of the previously published Lattice Greens Function methodology[1, 2, 3]. We have developed ...
متن کاملMonitoring of Crack Propagation in Concrete Using Embedded Piezoelectric Transducers
A concrete structure can be subject to several factors that may damage it during its service life. These factors are either be climatic, chemical or accidental. The security requirements are more and more speci c and severe. To ensure the safety of a structure, it is important to know its state and the properties of the materials that make it up. For this purpose, many tests has been developed....
