Multifield Coupling Mechanism of Unloading Deformation and Fracture of Composite Coal-Rock

Shock and Vibration, 2021
The deformation and fracture evolution of coal and rock under unloading are prone to sudden instability or dynamic damage. To solve the problem, this paper combines interdisciplinary theories such as damage mechanics and electromagnetic field theory. The

Local and non-local normalised equivalent strain functionals for cyclic fatigue [PDF]

, 2004
The concept of Cyclic Normalised Equivalent Strain Functionals (CNESnFs) suitable for lowcyclic fatigue is developed in this paper. It reduces any fatigue strength and durability model to a unique form what facilitates the models comparison ...

Mode I crack tip fields: strain gradient plasticity theory versus J2 flow theory

, 2019
The mode I crack tip asymptotic response of a solid characterised by strain gradient plasticity is investigated. It is found that elastic strains dominate plastic strains near the crack tip, and thus the Cauchy stress and the strain state are given ...

Causes of breakage and disruption in a homogeniser [PDF]

, 2010
Many authors have written in the past regarding the exact causes of breakage and disruption in a high pressure homogeniser, but there has been little agreement.

Study on the damage and fracture characteristics of coal rock based on the X-ray micro-CT scanning technology and statistical strength theory

Meitan kexue jishu, 2023
Coal rock dynamic disasters such as rockburst and gas outbursts pose severe threats to the safe and efficient mining of coal mines in China; however, the mechanical mechanisms of those disasters are still unknown. Therefore, the evolution law and constitutive model of damage and fracture of coal rock was emphatically studied, starting from the ...

Non-local energetics of random heterogeneous lattices

, 2010
In this paper, we study the mechanics of statistically non-uniform two-phase elastic discrete structures. In particular, following the methodology proposed in (Luciano and Willis, Journal of the Mechanics and Physics of Solids 53, 1505-1522, 2005 ...

Electro-Magnetic Earthquake Bursts and Critical Rupture of Peroxy Bond Networks in Rocks

, 2006
We propose a mechanism for the low frequency electromagnetic emissions and other electromagnetic phenomena which have been associated with earthquakes. The mechanism combines the critical earthquake concept and the concept of crust acting as a charging ...
