WebFeb 6, 2024 · The stress has units of Pascals and the strain-rate has units of 1/s, so the viscosity has units of Pa*s. The viscosity can be thought of as the resistance to flow. Higher viscosity indicates more resistance to flow. This can be seen more readily, by rewriting the equation above as: (1.5.2) ϵ ˙ = σ 2 η WebFeb 24, 2012 · How geological stresses affect rocks.
