Flow stress units

WebJun 22, 2024 · The level of stress at which failure occurs is the yield stress. Deformation may be brittle, where the material fractures, or ductile, where flow or creep occurs. Glacier flow. Glacier flow is a combination of the deformation of the ice and the bed, and sliding of ice over its bed. Glacier velocity therefore equals deformation plus basal sliding. In continuum mechanics, a power-law fluid, or the Ostwald–de Waele relationship, is a type of generalized Newtonian fluid (time-independent non-Newtonian fluid) for which the shear stress, τ, is given by where: • K is the flow consistency index (SI units Pa s ),
