WebThe Eyring equation (occasionally also known as Eyring–Polanyi equation) is an equation used in chemical kinetics to describe changes in the rate of a chemical reaction against temperature. It was developed almost simultaneously in 1935 by Henry Eyring, Meredith Gwynne Evans and Michael Polanyi. WebHence, in the high-stress region where yield occurs, the Eyring theory gives the relationship between strain-rate, ε̇, and applied stress, σ, as. where AE is a constant, R is the gas …
