The mechanical responses of dense packings of soft athermal spheres 45 degree sharkbite under a finite-rate shear are studied by means of molecular dynamics simulations.We investigate the volume fraction and shear rate dependence of the fluctuations in the shear stress and the interparticle contact number.In particular, we quantify them by defining the susceptibility as the ratio of the global to local fluctuations.The dermatom c3 obtained susceptibilities form ridges on the volume fraction-shear rate plane, which are reminiscent of the Widom lines around the critical point in an equilibrium phase transition.
