The failure characteristics of heat-treated sandstone subjected to splitting loading and the pore-crack distribution effects

Mechanical properties and damage constitutive model of tuff under stress–seepage coupling during low-temperature curing

Given the challenging conditions of high-alpine and high-altitude metal mining, complex factors affecting rock mass quality, and the intricate mechanisms of slope instability, this study focuses on the tuff from the high-alpine and high-altitude region of China. The deformation, strength, and failure characteristics of...

Mechanical response and failure mechanisms of sandstone under water–rock interaction: a multi-scale study and constitutive modeling

Mechanical properties and failure characteristics of granite with non-through cracks under thermal cycling.

Thermal cycling and pre-existing cracks significantly influence the mechanical response and damage evolution of granite in high-temperature rock engineering. To clarify their coupled effects, granite specimens with different prefabricated crack inclination angles (0°, 45°, and 90°) were subjected to different temperatu...

True‐triaxial deformation, cracking and strength failure characteristics of chemically corroded flawed sandstone

Damage evolution and microscopic failure characteristics of dense sandstone at different water contents.

To reveal the mechanical degradation, damage evolution, and failure mechanism of dense sandstone under varying water content, uniaxial compression tests were conducted on sandstone with different water contents. Combined with acoustic emission monitoring, scanning electron microscopy, and energy evolution analysis, con...

The Coupled Influence of Size and Strain Rate on the Failure Mechanism and Model Prediction of Fly Ash Concrete

This study investigates the mechanical behavior and failure characteristics of fly ash concrete under quasi-static to low-to-medium strain rate loading. Uniaxial compression tests were conducted on three specimen sizes under four strain rate conditions (totaling 12 working conditions), analyzing damage evolution and fa...
