Visco-elastoplastic constitutive model for remolded loess based on infinitesimalization of plastic elements

Yantu gongcheng xuebao
Based on the theory of infinitesimalization of plastic elements and infinite series, the visco-elastoplastic constitutive model for remolded loess is established through the triaxial creep tests under loading and unloading conditions and verified by the ...

Experimental study on cumulative deformation characteristics of coral sand under long-term cyclic loading

Yantu gongcheng xuebao, 2019
The drained triaxial shear tests on isotropic and K0 consolidation of coral sand samples taken from the South China Sea reveal that the consolidation path has a significant effect on the strength characteristics of the coral sand.

An Elasto–Plastic Hydro–Mechanical Model for Analyzing the Swelling Behavior of Heterogeneous Clay–Sulfate Rocks

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Swelling of clay‐sulfate rocks is a concern in geotechnical engineering that can damage infrastructure. In the historic town of Staufen in southwest Germany, geothermal drilling into a swellable anhydrite‐bearing clay formation resulted in water inflow and subsequent swelling, triggering ground heave and damage to more than 250 houses.

Cell‐Based Micro/Nanorobots: From Living Carriers to Living Therapeutic Specialists

SmartBot, EarlyView.
Cell‐based micro/nanorobots integrate evolutionarily acquired biological intelligence with engineered capabilities, offering new opportunities for precision medicine in vivo. However, the complex physiological environments of different organs pose significant challenges to their clinical translation.

Rotation capacity of continuous reinforced concrete slab strips revisited

Structural Concrete, EarlyView.
Abstract Rotation capacity is a key characteristic of statically indeterminate reinforced concrete structures, as it (i) enables bending moment redistributions, whether intentionally introduced through optimized reinforcement layouts or arising from unforeseen self‐equilibrated stress states, and (ii) promotes large rotations at failure load, thereby ...

Strong ground motion and structural damage in the 2023 Kahramanmaraş earthquakes: A comparative case study of numerical predictions and field observations

Structural Concrete, EarlyView.
Abstract On February 6, 2023, southeastern Türkiye was struck by two catastrophic earthquakes (Mw: 7.7 and Mw: 7.6) along the East Anatolian Fault Zone, causing extensive structural failures and significant loss of life. This study evaluates the seismotectonic characteristics of the sequence, analyzes strong ground motion data against the Turkish ...

Transcranial electric stimulation in chronic pain: Effects on quality of life, physical function, activity and clinical status

Journal of Neuropsychology, EarlyView.
Abstract Transcranial electric stimulation represents a promising non‐invasive neuromodulatory technique targeting maladaptive nociplastic changes in chronic pain (CP) with analgesic effects. However, its impact beyond pain reduction on broader outcomes such as quality of life (QoL) and physical function remains unclear.

The Ecology of Human Sleep (EcoSleep) Cohort Study: Protocol for a longitudinal repeated measurement burst design study to assess the relationship between sleep determinants and outcomes under real‐world conditions across time of year

Journal of Sleep Research, Volume 34, Issue 2, April 2025.
Summary The interplay of daily life factors, including mood, physical activity, or light exposure, influences sleep architecture and quality. Laboratory‐based studies often isolate these determinants to establish causality, thereby sacrificing ecological validity.

Effects of Ambient Moisture and Large‐Strain Dynamic Preloading on the Dynamic Properties of the EAC‐1A Regolith Simulant

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5701-5711, November 2026.
ABSTRACT The EAC‐1A lunar mare simulant, a silty sand, was selected by the European Astronaut Center (EAC) for use in the LUNA analogue facility's lunar simulation testbed. Its stress‐ and strain‐dependent shear modulus and damping ratio were determined via resonant column testing on specimens prepared either from ambient moisture material or oven ...
