The definition of ε neq stems from observations in the dynamic testing: conditioning induces softening (hence the sign), proportional to the conditioning strain amplitude (hence, the proportionality to ε max). WebSep 1, 2016 · Recently, a new dynamic hysteresis model (DHM) has been implemented in the ATP-EMTP. This three-component DHM consists of a static hysteresis model (SHM) [11] implemented as a rate-independent hysteretic inductor, and two resistive elements, linear and nonlinear, reproducing classical eddy-current and excess losses respectively.
