A widely accepted theory of slab avalanche formation assumes the existence of "super-weak" layers. Because a weak layer cannot effectively transmit the shear forces from the overburden snow, stress and strain-rate concentrations at the ends of the weak layer are generated. Fracture initiates at the higher end when the strain-rate concentration exceeds a critical value. 2, record 1, English, - super%2Dweak%20layer

Another important type of non-Newtonian fluid is a viscoplastic or "yield stress" fluid. This is a fluid which will not flow when only a small shear stress is applied. The shear stress must exceed a critical value known as the yield stress... for the fluid to flow. For example, when you open a tube of toothpaste, it would be good if the paste does not flow at the slightest amount of shear stress. We need to apply an adequate force before the toothpaste will start flowing. So, viscoplastic fluids behave like solids when the applied shear stress is less than the yield stress. Once it exceeds the yield stress, the viscoplastic fluid will flow just like a fluid. Bingham plastics are a special class of viscoplastic fluids that exhibit a linear behavior of shear stress against shear rate.... Examples of viscoplastic fluids are drilling mud, nuclear fuel slurries, mayonnaise, toothpaste, and blood. 1, record 2, English, - yield%20stress%20fluid

Les fluides à seuil sont des matériaux extrêmement courants dans l'industrie, en particulier pétrolière et agro-alimentaire. On peut citer comme exemples le yaourt, la mayonnaise, le dentifrice, la boue, etc. Pour faire couler ces matériaux, il est nécessaire d'appliquer une contrainte (force par unité de surface) supérieure à une valeur critique afin de casser leur structure interne. 3, record 2, French, - fluide%20%C3%A0%20seuil
