The Use of Tertiary Creep Rates in Ice at High Strains in Compression and Shearxamine ice deforming at <~10. s. and with no visible evidence of cracking or failure, thus strains > 20% take long times to establish in the laboratory. At these large strains, crystal anisotropy plays a most important role in the determination of creep rates..For initially isotropic ice, the concep作者: ANN 時(shí)間: 2025-3-22 01:17

Creep Constitutive Equations for Polycrystalline Ice and Effect of Microcracking rate of polycrystalline ice is largely controlled by processes occuring on non-basal planes. Three main models describing the transient behaviour of polycrystalline ice are presented and discussed.

Kinetics of Microcracking and Dilatation in Polycrystalline Icemodel can be applied for constant stress as well as constant strain-rate loading conditions. It is based on intragranular dislocation creep enhanced by grain-facet size cracks produced during deformation by the embrittlement process that is caused by an intergranular sliding mechanism.

Models for the Deformation Behavior of Viscoelastic Media with Distributed Damage and Their Applicabicted behavior is consistent with that of polycrystalline ice.
