We find that in simulations of quasi-statically sheared frictional disks, the shear jamming transition can be characterized by an abrupt jump in the number of force bearing contacts between particles. Thismechanicalcoordination number increases discontinuously fromZ= 0 toat a critical shear value, as opposed to a smooth increase in the number of geometric contacts. This is accompanied by a diverging timescalethat characterizes the time required by the system to attain force balance when subjected to a perturbation. As the global shearapproaches the critical valuefrom below, one observes the divergence of the time taken to relax to a state where all the inter-particle contacts have uniformly zero force. Above, the system settles into a state characterized by finite forces between particles, with the timescale also increasing as. By using two different protocols to generate force balanced configurations, we show that this timescale divergence is a robust feature that accompanies the shear jamming transition.Graphic abstract
