文摘
- •
Linear viscoelasticity was strictly differentiated from the nonlinearity.
- •
Material properties in linear viscoelastic stage were the reference properties.
- •
Viscoelastic stress, reference modulus & pseudostrain were rigorously established.
- •
The sole linear viscoelastic effect was eliminated to determine pseudostrains.
- •
Dissipated pseudostrain energies were determined for representative loading cycle.
