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 ...

Analysis of Shear Characteristics of Deep, Anchored Rock Mass under Creep Fatigue Loading
Advances in Civil Engineering, 2021 To study the influence of earthquakes and engineering disturbances on the deformation of deeply buried rock masses, shear tests were carried out on anchored sandstone rock masses, anchored marble rock masses, and anchored granite rock masses under creep ...

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 ...

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.

Understanding the creep behavior of shale via nano-DMA method
Energy Reports, 2021 Understanding the creep behavior of shale is essential to precisely predict borehole instability issues and model fracturing of unconventional shale reservoirs. In this study, the creep behavior of shale in micron scale is investigated by integrating the

Creep Rate and Creep Model of Rockfill
Procedia Engineering, 2012 AbstractDue to the test duration restriction, not only the creep strain but also the creep rate should be considered to establish the creep model of the rockfill. The creep rate decides whether the creep model deviates from the actual strain after the test duration.
