Deformation damage and acoustic emission characteristics of red sandstone under fatigue-creep interaction

Ju Wang et al.

Summary: Most engineering rock masses are under the interaction of fatigue load and creep load. Understanding of the fatigue or creep characteristics of rock is relatively mature, but the damage and failure characteristics under fatigue-creep interaction (FCI) are rarely studied. The study on red sandstone with prefabricated cracks showed that the elastic modulus tended to be stable, while the deformation modulus decreased nonlinearly after creep loading. Acoustic emission (AE) mainly occurred in the fatigue loading stage, and the level of AE increased with the crack angle. These research results have theoretical reference value for understanding the damage and failure characteristics of fractured rock mass under interaction.

Anisotropic fracture and energy characteristics of a Tibet marble exposed to multi-level constant-amplitude (MLCA) cyclic loads: A lab-scale testing

Y. Wang et al.

Summary: This study investigated the fatigue mechanical characteristics of marble with different interbed orientations under multi-level constant-amplitude cyclic loads. The results showed that the interbed structure has a significant impact on the mechanical properties of rocks, and different damage evolution characteristics were observed at different cyclic loading stages. Energy analysis and CT images confirmed that the rock structure controls the pattern of energy dissipation and release.

Energy dissipation and damage evolution for dynamic fracture of marble subjected to freeze-thaw and multiple level compressive fatigue loading

Y. Wang et al.

Summary: The study investigates the fatigue mechanical behaviors of marble under freeze-thaw treatment, showing that fatigue strength and strain energy decrease while irreversible volumetric deformation increases with the number of cycles. The rate of dissipated energy increases as the cyclic loading level grows. A coupling damage variable is proposed to describe rock damage evolution after freeze-thaw treatment and fatigue loading, with a damage evolution model established to fit the experimental data showing two-phase damage accumulation characteristics.

Experimental investigation of the mechanical behaviors and energy evolution characteristics of red sandstone specimens with holes under uniaxial compression

Zhichao He et al.

Summary: The research showed that the mechanical behaviors and energy evolution characteristics of rock specimens with hole defects are significantly influenced by the number and arrangement of holes. The compressive strength decreases with an increase in the number of boreholes, while the hole arrangement angle has a stronger effect on energy storage coefficient and compressive strength.

Experimental study of energy dissipation characteristics and crack coalescence modes of cracked sandstone under different cyclic loading paths

Kang Peng et al.

Summary: This study investigated the effects of different loading modes on cracked sandstone, finding that cyclic loading increased deformation modulus compared to uniaxial compression. The dissipated energy densities of the samples increased differently under increasing and constant lower stress limit cyclic loading. The study also defined crack types and found that cyclic loading led to more cracks and surface spalling compared to uniaxial compression.

Grzegorz Ludwik Golewski

Summary: The paper discusses the use of innovative optical and contactless DIC techniques to examine fracture processes in concrete with fly ash under shear loading. It investigates the critical stress intensity factor K-IIc and crack characteristics in loaded specimens, proposing a new concept for assessing fracture toughness of composites. It also presents a sophisticated solution for measuring actual crack path length (ALCP) and demonstrates the different brittleness and quasi-plastic behavior of unmodified concrete versus composites based on binary binders during the fracture process.

Effects of pre-existing single crack angle on mechanical behaviors and energy storage characteristics of red sandstone under uniaxial compression

Lei Xu et al.

Summary: The study investigated the effects of pre-existing single crack angles on the mechanical behaviors and energy storage characteristics of red sandstone. Results showed that peak compressive strength, peak strain, and elastic modulus of specimens increase with crack angle, and specimens exhibited anti-N-type shear failure. Energy densities at peak strength were quantitatively determined based on linear energy storage law, and damage constitutive equations were obtained for specimens with different crack angles.
