Soft yield stress materials, which are ubiquitous around us, fail when the imposed stress crosses a critical threshold. A well-known dynamical response to the applied stress is the phenomenon of creep where the cumulative strain grows sublinearly with time. Using extensive numerical simulations, we study the response of model amorphous solids, having diverse preparation histories, to applied shear stress.  Our macroscopic measurements provide an opportunity to test different theoretical predictions. And, our microscopic analysis provides insight into the spatiotemporal elastoplasticity underlying the macroscopic observations.
