We study theoretically the dynamics of soft glassy materials during theprocess of stress relaxation following the rapid imposition of a shear strain.By detailed numerical simulations of a mesoscopic soft glassy rheology modeland three different simplified continuum fluidity models, we show that adramatic shear localisation instability arises, in which the strain fieldsuddenly becomes heterogeneous within the sample, accompanied by a precipitousdrop in the stress. Remarkably, this instability can arise at extremely longdelay times after the strain was applied, due to the long-term memory inherentto glassy systems. The finding that a catastrophic mechanical instability canarise long after any deformation could have far reaching consequences formaterial processing and performance, and potentially also for delayedgeophysical phenomena.
