Study on Numerical Simulation of Overburden Fracture Development Characteristics and Prediction of Water-Conducting Fracture Zone Height in Shallow Coal Seam Mining

Geofluids
The northern Shanxi mining region, a pivotal coal-rich area in China, is characterized by substantial reserves of shallow coal seams and distinctive geological mining conditions that exacerbate overburden rock fissure development.

Fractional Calculus for Continuum Mechanics - anisotropic non-locality

, 2015
In this paper the generalisation of previous author's formulation of fractional continuum mechanics to the case of anisotropic non-locality is presented. The considerations include the review of competitive formulations available in literature.

A Computationally Efficient p-Refinement Finite Element Method Approach for the Fracture Analysis of Axially Cracked Pipes with Composite Patch Reinforcement

Applied Sciences
Cylindrical shells are widely used in pipelines, pressure vessels, and aircraft fuselages due to their efficient internal pressure distribution. However, axial cracks caused by fatigue, environmental effects, or mechanical loading compromise structural ...

Progressive damage and rupture in polymers

, 2017
Progressive damage, which eventually leads to failure, is ubiquitous in biological and synthetic polymers. The simplest case to consider is that of elastomeric materials, which can undergo large reversible deformations with negligible rate dependence. In

Research on a risk prediction model of gear tooth flank fracture based on multiaxial stress fatigue criterion

Jixie chuandong
ObjectiveTooth flank fracture is a contact fatigue failure mode of high-cycle/ultra-high-cycle fatigue damage where cracks initiate due to material damage at deep locations inside the tooth.

Discussion on multi-sphere responses and damage reduction-oriented geological guarantees in coal mining

Meitian dizhi yu kantan
ObjectiveCoals serve as a cornerstone for ensuring the energy security of China. However, coal mining activities break the original in situ stress equilibrium, triggering multi-sphere damage conduction and coupling responses in the lithosphere ...
