Viscoelastic–plastic creep constitutive model of frozen soil [PDF]
In accordance with the twin-shear unified strength theory and the improved Nishihara model, a viscoelastic–plastic creep constitutive function of frozen soil has been established based on the associated flow rules, and the viscoelastic–plastic soft matrix is further derived from numerical calculations.

Shear creep characteristics and constitutive model of limestone
Abstract The characters of limestone in weak interlayer of a high rocky slope in Xuzhou, China, are studied by shear static test and shear creep test. The results show that limestone specimens have attenuation creep properties and constant rate creep properties, almost have no accelerated creep properties.
