A Viscoelastic Constitutive Model For Constant Rate Loading At Different Relative Humidities

M. Pecht and H. Haslach, Jr.


A nonlinear viscoelastic strain model is developed for time-dependent ramp loading at different constant relative humidities.  The model is applied to edgewise compression data on kraft paper linerboard at various constant relative the durability, written as a function of three material constants.  The model generalizes non-viscoelastic, moisture-dependent creep models.
