Simulation of the interactions between hydraulic and natural fractures using a fracture mechanics approach

Journal of Rock Mechanics and Geotechnical Engineering, 2019
HYDROCK method aims to store thermal energy in the rock mass using hydraulically propagated fracture planes. The hydraulic fractures can interact with the pre-existing natural fractures resulting in a complex fracture network, which can influence the ...

Introducing platform surface interior angle (PSIA) and its role in flake formation, size and shape.

PLoS ONE, 2020
Four ways archaeologists have tried to gain insights into how flintknapping creates lithic variability are fracture mechanics, controlled experimentation, replication and attribute studies of lithic assemblages.

Multi-parameter fracture mechanics

Fracture and Structural Integrity, 2019
A mixed-mode geometry has been chosen to investigate a crack propagation using the multi-parameter fracture mechanics concept. The so-called Williams’ series expansion is used for the crack-tip stress field approximation.

3D Numerical Solution for Natural Fracture Distribution in Tight-Sand Reservoirs Based on Damage Mechanics with Sets of 2D Seismic Data

Applied Sciences
Natural fracture development in tight-sand gas reservoirs is strongly controlled by tectonic evolution yet remains difficult to characterize using conventional seismic interpretation due to limited resolution. This study presents a damage-mechanics-based

Comparison of the constraint parameters in elastic-plastic fracture mechanics

Fracture and Structural Integrity, 2019
To describe the effect of crack-tip constraint on the stress field for finite cracked bodies, the following most widely used constraint parameters can be employed in elastic-plastic fracture mechanics, namely, local triaxiality parameter, constraint ...

Numerical modeling of thermally-induced fractures in a large rock salt mass

Journal of Rock Mechanics and Geotechnical Engineering, 2018
Numerical modeling of thermally-induced fractures is a concern for many geo-structures including deep underground energy storage caverns. In this paper, we present the numerical simulation of a large-scale cooling experiment performed in an underground ...
