We present a study of crack patterns in a layer of laponite gel allowed to dry in a static electric field. Crack …

Experiments have been conducted to study crack patterns forming in drying films of laponite. The patterns have been … analysed to observe the self-similarity of the structure, with respect to crack width. Ped-size distributions and other … cracks, when plotted on a log–log plot, versus the lowest crack width observable shows two linear regimes. An idealized model …

. Brittle fracture of the same material with different quenched disorders is simulated. Fractal dimension of crack fluctuates … with quenched disorder. It seems that it is impossible to have a universal fractal dimension of crack in brittle fracture …

propagation of a crack through the fiber bundle. In addition, the crack velocity is not constant, depending on the number of …

Shaft crack is a very dangerous and frequent fault in rotating machine, but how to locate and configure it is just an … inverse problem and not easy to tackle. In this paper, a genetic algorithms based method for shaft crack detection is proposed … and described, which formulates the shaft crack detection as an optimization problem by means of finite element method and …

A pulse solution for a propagating crack resticking after breakage is presented for mode III crack in a two …

Time-domain boundary element method (BEM) for elastodynamic crack analysis is presented in this paper. Special …, namely, “crack-tip elements” behind crack-tips while constant elements away from crack-tips. The use of “crack-tip elements …” takes the proper local behavior of the crack opening displacements (COD) at crack-tips into account, and it makes an …

crack-tip velocity increases above a certain threshold. In this paper we extend a simple phenomenological model and a … scaling analysis for the growth of crack surfaces in inhomogenous solids by introducing explicitly the effects of the stress …
