On the creep behavior of uranium dioxide
Materials Science and Engineering, 1982The creep data for stoichiometric polycrystalline uranium dioxide (UO2) obtained in several compression investigations are analyzed using the Dorn equation together with deformation mapping, and it is shown that the data are divisible into three regions of deformation, depending on the value of the normalized stress.

Transient behavior of diffusion-induced creep and creep rupture
Metallurgical Transactions A, 1975Steady state solutions to three types of diffusion problems: creep, grain boundary sliding and intergranular crack growth, have been published in the literature. This paper considers, in detail, the events which occur between the time when the external stress is applied and the time when the steady state is eventually reached.

International Journal of Rock Mechanics and Mining Sciences, 2015
Abstract Several creep tests (lasting more than one year) were performed to study the delayed mechanical behavior of Boom clay under the hydro-mechanical coupling effect. To prevent the soil from swelling as much as possible during re-saturation, the samples were submitted to a confining pressure close to the in situ effective mean stress (2.5 MPa ...

Creep behavior of submarine sediments
Geo-Marine Letters, 1984A series of experiments on drained creep of marine sediment indicates that strength degradation results from the creep process, which implies an associated reduction in slope stability. Furthermore, the highest creep potential of a sediment may be at its preconsolidation stress.

Creep behavior of electrorheological fluids
Journal of Rheology, 1994Composite particles consisting of a polymer core and an inorganic shell were formed by suspension polymerization. For suspensions in a silicone oil, the steady-shear viscosity and creep behavior were measured in electric fields up to 2.0 kV mm−1. Although the polymer core is not ER active, the suspensions of composite particles show a striking increase

Creep Behavior of Shale: Nanoindentation vs. Triaxial Creep Tests
Rock Mechanics and Rock Engineering, 2020In this study, three shale samples from the Wolfcamp Formation in Permian basin were selected and studied for creep behavior using two different methods at macro- and micro-scale: triaxial and nanoindentation creep tests. The triaxial creep test showed the effects of axial differential stress on the creep behavior of shale rocks including the strain ...

Compressive creep behavior of Nb5Si3
Scripta Metallurgica et Materialia, 1995Abstract The compressive creep data for Nb5Si3 can be described by the following relation: e = 2.773 × 10 −22 kT exp ( −28125 T σ 0.8±0.1 in the temperature range of 1200 to 1400 °C and stress regime of 52 to ~174 MPa. Based on a stress exponent of ~1, and activation energy of 234 kj mol , it is suggested that creep ...

Computation of the creep behavior of thermoplastics
Polymer Engineering & Science, 1978AbstractThe dimensioning of structural parts made of plastics requires the knowledge of the material parameters which depend on the processing and, loading conditions. In this paper, the possibility of describing the stress‐, temperature‐, and time‐dependent deformation behavior of thermoplastics below the linear viscoelastic limit is presented, using ...

Creep behaviors evaluation of Incoloy800H by small punch creep test
Materials Science and Engineering: A, 2017Abstract In this paper, creep properties estimation of Incoloy800H under various loads and temperatures were performed experimentally and analytically. Compared to standard creep test, a similar creep character could be obtained by small punch creep test. On the basis of geometrical shape of deformed specimen, we proposed a modified geometrical model.
