In Situ Deformation Analysis of a Fracture in Coal under Cyclic Loading and Unloading [PDF]
Energies, 2021 The deformation analysis of fractures is vital for advantageous development of oil and gas fields, especially the coalbed methane (CBM) reservoir, since the change of fracture parameters can be directly evaluated through fracture deformation analysis. Then the flow capacity of CBM and the effect of various stimulation methods can be analyzed.

Influence of Loading Rate on the Energy Evolution Characteristics of Rocks under Cyclic Loading and Unloading [PDF]
Energies, 2020 To analyse the effect of loading rate on the energy evolution of rocks under cyclic loading and unloading, tests on saturated limestone were conducted at loading rates of 0.15, 0.2, and 0.3 mm/min, and the evolution characteristics of plastic, elastic, dissipation, and input energies were examined under different loading rates.

Energy Behaviour of Coal Failure under Uniaxial Cyclic Loading/Unloading
, 2023 Coal failure is often the precursor of dynamic disaster. The energy evolution behaviour at different stress values was analysed under the gradation of equal amplitude cyclic loading/unloading.

Study on constitutive model of coal rock damage under graded cyclic loading and unloading
, 2022 Taking coal as the research subject, the damage mechanical properties of coal were studied by grading cyclic loading and unloading tests. Using the Weibull statistical distribution and the introduction of damage variable D, a damage constitutive model ...

Chondrocyte deformation during the unloading phase of cyclic compression loading
Journal of BiomechanicsCell volume and shape changes play a pivotal role in cellular mechanotransduction, governing cellular responses to external loading. Understanding the dynamics of cell behavior under loading conditions is essential to elucidate cell adaptation mechanisms in physiological and pathological contexts.

Tehnički vjesnik, 2020 This paper mainly explores the deformation characteristics of limestone specimens under constant load cyclic loading. For limestone specimens under uniaxial compression, the stress-strain curve can be divided into three stages: compaction stage, elastic stage and sudden failure stage. Under cyclic loading, the hysteresis loop on the stress-strain curve

FEBS Open Bio, EarlyView.14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.
