Creep characteristics of frozen soils
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1979Abstract Consideration of the creep characteristics of frozen soil is required when it is used for the construction of retaining walls. It is generally accepted that there are three kinds of frozen soils, i.e., frozen soil without ice lenses, frozen soil with layers of ice lenses and frozen soil with needle-like ice lenses, influenced by freezing ...

Compression Creep Characteristics and Creep Model Establishment of Gangue
Geotechnical and Geological Engineering, 2016How to describe the compression creep behavior of gangue is very essential for the design of gangue backfilling mining. In this paper, compression tests of two kinds of gangue are studied, finding that logarithmic function is suitable for describing its equal-time stress–strain relationship. Stress–strain–time relationship is proposed through modifying

Creep characteristics of piezoelectric actuators
Review of Scientific Instruments, 2000A major limitation of piezoelectric translator (PZT) actuators is their lack of accuracy originated from the hysteresis and creep. Nevertheless the creep phenomenon is an important factor in many applications of PZT actuators, but it has been investigated less frequently in comparison with the displacement hysteresis.

Long-term creep and creep rupture characteristics of TiAl-base intermetallics
Materials Science and Engineering: A, 2009Abstract The present study investigates creep in three TiAl-base intermetallic alloys, Ti–48Al–2Cr–2Nb–1B, Ti–46Al–7Nb–0.6Cr–0.2Ni–0.1Si and Ti–46Al–2W–0.5Si–0.7B (all at.%), in the range of rupture times up to 25 000 h. Creep behaviour of the individual alloys at 1023 K is assessed and compared and reasons for creep strength variations are discussed.

Characteristics of creep deformation in ceramics
Materials Science and Technology, 1991AbstractThe creep mechanisms in ceramics are reviewed briefly and then compared with experimental data. It is shown that there are three major types of creep behaviour: a stress exponent close to 5 due to control by dislocation climb and fully ductile behaviour; a stress exponent close to 3 due to control by climb from Bardeen–Herring sources and less ...

Characteristics of creep in polycaproamide cloth
Fibre Chemistry, 1998The applicability of a fast method of determining the creep characteristics by brief measurements, developed for synthetic fibres, to polycaproamide cloth was demonstrated. The advantages of the proposed method are the minimum characteristics used and for this reason, the stability of the numerical values of these characteristics.

Creep deformation characteristics of rubberised structural concrete
Construction and Building Materials, 2021Abstract The influence of replacement of fine mineral aggregates with crumb tyre rubber of different particle sizes (2.36, 1.18 and 0.425 mm) on creep and shrinkage of structural rubberised concrete (rubcrete) is investigated. Rubcrete specimens were made using plain Portland cement (PC), 0.60 w/b ratio, crushed andesite coarse aggregate and a 90/10 ...

Creep characteristics and time-dependent creep model of tunnel lining structure concrete
Mechanics of Time-Dependent Materials, 2020A creep test of concrete with different moisture contents is conducted using the MTS815.02 test system to investigate the creep damage law of concrete with respect to stress and time. The creep properties of concrete under hydration and the relationship between water content and concrete creep deformation are analyzed.
