Journal ArticleDOI
Dynamic instabilities of fracture under biaxial strain using a phase field model.
Hervé Henry,Herbert Levine +1 more
TL;DR: This model is able to accurately reproduce the different behavior of cracks and reproduces well observed supercritical Hopf bifurcation and is therefore the first simulation which does so.
Journal ArticleDOI
Scroll waves in isotropic excitable media: linear instabilities, bifurcations, and restabilized states.
Hervé Henry,Vincent Hakim +1 more
TL;DR: The linear stability spectrum of untwisted and twisted scroll waves is computed for a two-variable reaction-diffusion model of an excitable medium to obtain a number of matrix elements characterizing the long-wavelength deformations of scroll waves.
Journal ArticleDOI
Study of the branching instability using a phase field model of inplane crack propagation
TL;DR: In this paper, the phase field model of crack propagation is used to study the dynamic branching instability in the case of inplane loading in two dimensions, and the critical speed at which the instability starts is about 0.48cs.
Journal ArticleDOI
Thermal fracture as a framework for quasi-static crack propagation
TL;DR: In this paper, the authors address analytically and numerically the problem of crack path prediction in the model system of a crack propagating under thermal loading and show that one can explain the instability from a straight to a wavy crack propagation by using only the principle of local symmetry and the Griffith criterion.
