Glen flow law
WebSep 29, 2024 · The Glen law is characterized by a stress exponent n of ∼ 3 and is based on the classic laboratory experiments of Glen (1952, 1955) and numerous subsequent experiments on coarse-grained polycrystalline ice. WebJul 10, 2024 · We have demonstrated that expressing the pressure dependence of the rate factor ( Eqn (3)) of Glen’s flow law only by a dependence on the temperature relative to pressure melting is consistent, within the rather large uncertainties, with measured values of the activation volume.
