Modified true triaxial Hoek-Brown criterion considering intermediate principal stress effect

Meitan kexue jishu
In order to improve the Hoek-Brown strength criterion not considering the influence of intermediate principal stress on rock strength, the evolutions of rock strength were investigated according to the results of the rock true triaxial compression test ...

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.

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.

The Long Shadow of Karl Weierstraß Over the Calculus of Variations

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT At first glance, it appears that the contents of Karl Weierstraß's (1815–1897) lecture courses on the calculus of variations were made available to the public only in the seventh volume of his Mathematische Werke, and thus not until 30 years after his death.

An Improved True Triaxial Hoek–Brown Strength Criterion

工程科学与技术, 2023
Hoek–Brown strength criterion has been widely used in rock and rock mechanics analysis, rock slope stability analysis, rock tunnel design, and other fields, but the conventional Hoek–Brown strength criterion does not consider the influence of ...

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 ...

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 ...
