Mechanical properties of saturated remolded loess under different stress paths
Shuiwen dizhi gongcheng dizhi, 2022 The mechanical properties of soil often vary with stress state and stress paths. In order to investigate the mechanical properties of saturated soil under vertical loading and constant shear stress path, saturated remolded loess samples are prepared ...

Characteristics of structural loess strength and preliminary framework for joint strength formula
Water Science and Engineering, 2014 The strength of structural loess consists of the shear strength and tensile strength. In this study, the stress path, the failure envelope of principal stress (Kf line), and the strength failure envelope of structurally intact loess and remolded loess ...

Geomechanics in Depleted Faulted Reservoirs
Energies, 2020 This paper examines the impact of the effective stresses that develop during depletion of a faulted reservoir. The study is based on finite element modeling using 2D plane strain deformation analysis with pore pressure and elastoplastic deformation of ...

Basin excavation using robotic manipulator of geo-centrifuge at NHRI
Yantu gongcheng xuebao, 2020 The simulation of basin excavation process of the sheet-pile wharf in the centrifugal modeling tests is mostly carried out under 1g. Also an elevation of 1g to Ng is added compared with the prototype, which results in the same stress state but different ...

Stress Management: A New Path to Pluripotency [PDF]
Cell Stem Cell, 2014 Two recent papers in Nature describe a remarkable new technique for reprogramming somatic cells back to the embryonic state. Obokata et al. (2014a, 2014b) show that applying stressful stimuli can convert mature cells into progenitors capable of generating all three embryonic germ layer lineages, as well as placental tissue.

CORRESPONDENCE BETWEEN STRAIN PATH AND STRESS PATH IN PLASTIC DEFORMATION
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series A, 1996 This paper deals with the connections between the local geometries of associated paths of stress and strain under plastic deformation. This is a classical topic; nevertheless, some practically important aspects remain to be investigated in depth. The studies of the mutual relations between these paths reported in the literature have been performed in ...

Analysis of deformation mechanism of soft soil reinforcement by vacuum preloading
Rock and Soil Mechanics, 2021 Based on the changes of total stress and pore water pressure in the spring model, the mechanism of vacuum preloading consolidation is studied by theoretically discussing the consolidation behavior of soil in vertical and horizontal directions with ...

Acute stress impairs visual path integration
Neurobiology of Stress, 2023 Acute stress exerts substantial effects on episodic memory, which are often mediated by glucocorticoids, the end-product of the hypothalamic-pituitary-adrenal axis. Surprisingly little is known, however, about the influence of acute stress on human spatial navigation. One specific navigational strategy is path integration, which is linked to the medial

Mechanical response of grading loading and unloading of backfill sand under confinement constraint
Shenzhen Daxue xuebao. Ligong ban, 2023 In subgrade and levee projects, local subsidence problems often occur due to insufficient compaction of backfill sand. In order to reduce the possibility of such damage, the three-dimensional stress-strain testing technology is used to study the ...
