Hypoplasticity for Sand With Explicitly Defined Asymptotic States

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT A hypoplastic model for sand with defined asymptotic states is proposed. The fourth‐order tensor A$\mathsf {A}$ is defined by modifying the compression relation of the reference hypoplastic model by von Wolffersdorff (HP). This enables the mathematical formulation of a hypoplastic model for sand including the asymptotic state boundary surface (

Effect of Double Annealing on the Microstructure and Mechanical Properties of a Medium Manganese Steel

steel research international, EarlyView.
A double intercritical annealing strategy is proposed to tailor the multiphase microstructure and mechanical response of a medium‐Mn steel. The treatment produces an ultrafine mixture of ferrite, martensite and multiple austenite populations with graded thermal and mechanical stability, formed through austenite reversion and controlled retransformation.

Prediction of pregnancy following transfer of in‐vitro produced embryos using recipient health records, accelerometer sensors and meteorological data in Australian dairy cows

Australian Veterinary Journal, EarlyView.
Embryo transfer (ET) in dairy cattle has long been used for the dissemination of elite genetics. However, achieving consistently high pregnancy rates remains a major challenge, particularly in high‐producing lactating dairy cows receiving in‐vitro produced (IVP) embryos.

True triaxial modeling test of high-sidewall underground caverns subjected to dynamic disturbances

Journal of Rock Mechanics and Geotechnical Engineering
Seismicity resulting from the near- or in-field fault activation significantly affects the stability of large-scale underground caverns that are operating under high-stress conditions.

Metabolic Adaptations to Weight Loss in Obese Senior Dogs: Effects on Energy Expenditure, Protein Turnover, and Voluntary Physical Activity

Journal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Implications of obesity and weight loss (WL) for energy and protein metabolism are not fully understood, particularly in senior dogs. This study evaluated changes in body composition, energy expenditure (EE), protein turnover (PT), and voluntary physical activity (VPA) in senior dogs in maintenance and after 10% and 20% WL.

Analytical Methodology to Determine Thermally Induced Soil Deformation From Laboratory Data

International Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 16, Page 5868-5890, November 2026.
ABSTRACT Experimental laboratory investigations underlie most of the knowledge about the mechanics of soils under non‐isothermal conditions and their thermally induced deformation. Despite advances, the understanding of thermally induced deformation of soils remains inconsistent, hindering the development of a coherent framework that can advance ...

Microdynamic mechanical properties and fracture evolution mechanism of monzogabbro with a true triaxial multilevel disturbance method

International Journal of Mining Science and Technology
The far-field microdynamic disturbance caused by the excavation of deep mineral resources and underground engineering can induce surrounding rock damage in high-stress conditions and even lead to disasters.

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 ...
