Instantaneous deformation
Nettet19. feb. 2024 · This is the instantaneous deformation of the material upon application of the stress. This deformation disappears entirely as soon as the stress is canceled. It is modeled by a purely elastic spring of stiffness E. The stress–strain relation is given by Hooke's law: \sigma \left ( t \right) = E\varepsilon \left ( t \right). (1) Viscoelasticity Nettet12. mai 2024 · The results indicate that freeze–thawed soil produces smaller creep deformation and instantaneous deformation than the unfrozen soil. On a micro-level, during the creep process, the soil skeleton reaches a new structure balance with smaller pore volume and pore area. But the diameter of the maximum pore increases.
