Dynamic crack propagation drives catastrophic material failures. A key aspect in the problem is the stress concentration at the tip of cracks, which makes the failure behavior observed at the macroscopic scale very sensitive to inhomogeneities in the material micro-structure, or, in local loading, down to very small scale. Stress concentration and redistribution of stresses during crack growth, indeed, couple many space and time scales. They stretch from the macroscopic dimension of the sample, L, down to the size of the so-called fracture process zone, which embeds all the dissipative process involved in the creation of new fracture surface area). Elastodynamics and continuum fracture theory a priori provide the relevant tools to describe ...
