Nonlinear Moisture Effects on Long-Term Creep at Stationary and Nonstationary Conditions

摘要

Linear and nonlinear effects of moisture on viscoelastic behavior at creep are revealed for polyester and Nylon and the features are compared. A procedure for the estimation of character of the moisture effect on viscoelastic response is elaborated. The function of the reduced creep compliance is introduced for the creep data treatment and unequivocal determination of the moisture reduction function. Long-term creep at nonstationary moisture conditions is investigated.
