The stability of steady shear flows of some viscoelastic fluids relative to small perturbations in the initial data is examined. It is shown that at all values of the steady shear rate where the flow curve exhibits a zero or negative slope the flow is unstable. This conclusion is corroborated by exi
## Abstract There is a growing interest in developing numerical tools to investigate the onset of physical instabilities observed in experiments involving viscoelastic flows, which is a difficult and challenging task as the simulations are very sensitive to numerical instabilities. Following a rece
