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 Nettet1. jun. 2024 · A decrease in temperature reduces the instantaneous and creep deformations of the rocks at all levels of stress. In addition, a decrease in temperature exponentially attenuates the total creep and viscoplastic strains of the rocks. 0°C is a critical point for the reduction of the total creep and viscoplastic strains of the rocks.
