It is common for the fractured zone around dynamic faults to contain tensile cracks. The effect of Poisson's ratio (ν) on the creation of these cracks was investigated in this study as a function of the dynamic minimum strain energy density criterion (MSED-Criterion). In addition, the effect of rupture speed (c), friction coefficient (f), fault inclination angle (β) and confining stress (Ko) were taken into account. The MSED-Criterion permits the study of the creation of tensile cracks in brittle and ductile shear zones. It was found that by increasing Poisson's ratio, the rock behavior transfers gradually from brittle to ductile and as a consequence, the branching angle and fracture toughness increase. Whenever the rock mass tends towards ductile behavior, the possibility of creating tensile branches decreases. Ductile shear zones can sustain stresses greater than brittle zones before tensile branches are formed around dynamic … Journal Papers
