TLDR
In this article, a method for determining average volumetric strain in cylindrical test specimens is presented, which gives direct measurement of the lateral component of VOLUME 7, 2019, and because axial strain is the independent variable in deformation-controlled tests, the results are given as lateral volUMetric strain-axial strain curves.About:

Ground Response Curves for Rock Tunnels
TL;DR: In this paper, a closed-form solution is presented for an elastic-brittle-plastic material behavior model in which post-peak dilatancy occurs at a constant rate with major principal strain.

A Review of the Tensile Strength of Rock: Concepts and Testing
TL;DR: In this article, a review of the tensile strength of rock was conducted to determine the relationship between DTS and BTS and examine the validity of estimating tensile strengths from other measured properties, such as the crack initiation (CI) threshold.

A study of the mechanical behaviour of coal for pillar design
T.P. Medhurst,Edwin T. Brown +1 more
TL;DR: A series of triaxial compression tests was carried out on 61, 101, 146 and 300mm diameter coal samples to investigate the effects of scale on the mechanical behavior of coal.

A mobilized dilation angle model for rocks
Xingguang Zhao,Ming Cai +1 more
TL;DR: In this article, a mobilized dilation angle model considering the influence of both confining stress and plastic shear strain is proposed to predict the volumetric-axial strain relationships, and the predictions are found to be in good agreement with experimental results.

Theory of elasticity
TL;DR: The theory of the slipline field is used in this article to solve the problem of stable and non-stressed problems in plane strains in a plane-strain scenario.

Dilatancy in the Fracture of Crystalline Rocks
TL;DR: In this paper, the authors measured volume changes of a granite, a marble, and an aplite during deformation in triaxial compression at confining pressure of as much as 8 kb.
Journal ArticleDOI
The failure of rock
TL;DR: In this paper, an analysis of the energy changes associated with the extension of Griffith cracks in tension and compression is made, which shows that the non-elastic behaviour can be described by a curved Griffith locus in the strain-stress plane.
