摘要: We present a numerical study model of shear bands in rocks with non-associated plastic flow rule. The system drives spontaneously into state which the length distribution follows power law and where spatial organization appears to be fractal. local gradients deviatoric strain rate has different scaling exponents for each moment we calculate discuss. Samples granodiorite from Pyrenees sheared under high confining pressure are analyzed their properties compared results.
