This article is a personal review of the historical developments of digital image correlation
(DIC) techniques, together with recent important advances and future goals. The historical …

Geomaterials (ie rock, sand, soil and concrete) are increasingly being encountered and
used in extreme environments, in terms of the pressure magnitude and the loading rate …

Natural rock joints with infilling materials such as clay, broken rock fragments, or even
cement mortar infusion material are common in the field of rock engineering. The fracture …

We present a detailed experimental procedure for the quantitative determination of
mechanical properties and full-field strain measurement of rock material under dynamic …

A non-contact optical method for strain measurement applying three-dimensional digital
image correlation (3D DIC) in uniaxial compression is presented. A series of monotonic …

Abstract The Digital Image Correlation (DIC) method is commonly used in fracture analysis,
but it has limitations in measuring discontinuities, which is crucial in fracture analysis. To …

Discontinuities widely exist in natural rocks. To investigate the progressive micro-cracking
process and failure mechanism of fissured rocks, a series of biaxial compression tests were …

Brazilian tests are used to determine tensile strengths of rocks. Failure mechanisms, and the
strengths determined, are influenced by the configuration of the load contacts. Most research …

This study aimed to investigate the acoustic emission (AE) behavior of rock salt under
combined creep and fatigue. The loading path was in a stress-controlled mode and …

Acoustic emission (AE) and digital image correlation were used to monitor mode I fracture in
center notch and smooth boundary specimens. The AE source was characterized as a …
