Comparative Study of Creep and Stress Relaxation Behaviour during Ageing of 7050 Aluminum Alloy
Metals, 2023 This work focuses on quantitatively investigating the relationship between creep and stress relaxation of 7050 aluminum alloy at ageing temperatures. The creep strain rates, creep exponent, n, and activation energy were extracted from both the creep and ...

Triaxial creep test and model study of red sandstone based on Weibull distribution
Shuiwen dizhi gongcheng dizhi, 2023 At present, the creep problem of underground engineering surrounding rock still exists, and the creep theory needs to be further enriched. In essence, rock creep is a process of constant accumulation of damage.

Brittle Creep and Viscoelastic Creep in Lower Palaeozoic Shales from the Baltic Basin, Poland
Energies, 2021 The paper analyses the mechanical properties of shales from the Baltic Basin, focusing on creep strain in conditions of variable stress and elevated temperature (85 °C). Rock samples were collected from drill cores from various depths between 3600–4000 m.

An elastic-viscoplastic creep model for describing creep behavior of layered rock
Frontiers in Materials, 2023 To describe the full-stage creep behavior of layered rock accurately, a new elastic-viscoplastic creep model is proposed based on fractional order theory in this manuscript, which consists of a Hooke elastomer, a fractional Abel dashpot, a Kelvin body ...

The Effect of Specimen Size and Test Procedure on the Creep Behavior of ME21 Magnesium Alloy
Crystals, 2021 Lightweight constructions and materials offer the opportunity to reduce CO2 emissions in the transport sector. As components in vehicles are often exposed to higher temperatures above 40% of the melting temperature, there is a risk of creep.

Creep and Creep-Fatigue Crack Growth [PDF]
International Journal of Fracture, 2015 Creep and creep–fatigue considerations are important in predicting the remaining life and safe inspection intervals as part of maintenance programs for components operating in harsh, high temperature environments. Time-dependent deformation associated with creep alters the crack tip stress fields established as part of initial loading which must be ...

Description of Concrete Creep under Time-Varying Stress Using Parallel Creep Curve
Advances in Materials Science and Engineering, 2016 An incremental format of creep model was presented to take account of the development of concrete creep due to loading at different ages. The formulation was attained by introducing a horizontal parallel assumption of creep curves and combining it with ...
