Proppant-Induced Opening of Hydraulically Created Fractures
Open Geomechanics, 2021 The paper examines the problem of the open configuration created when a hydraulic fracture fluid containing a granular proppant is introduced into the fracture. The mathematical modelling examines the problem of a Griffith crack that is wedged open by a

Damage Detection of Axially Loaded Beam: A Frequency-Based Method [PDF]
Civil Engineering Infrastructures Journal, 2016 The present study utilizes an analytical method to formulate the three lowest modal frequencies of axially-loaded notched beam through both crack location and load level in a specific format that can be used in existing frequency-based crack ...

Tracer Dispersion in Rough Open Cracks [PDF]
, 1998 Tracer dispersion is studied in an open crack where the two rough crack faces have been translated with respect to each other. The different dispersion regimes encountered in rough-wall Hele-Shaw cell are first introduced, and the geometric dispersion ...

Modified and Simplified Sectional Flexibility of a Cracked Beam
Journal of Applied Mathematics, 2012 This paper presents a new sectional flexibility factor to simulate the reduction of the stiffness of a single-edge open cracked beam. The structural model for crack of the beam is considered as a rotational spring which is related to the ratio of crack ...

Evolution of mud-crack patterns during repeated drying cycles [PDF]
, 2010 In mud, crack patterns are frequently seen with either an approximately rectilinear or hexagonal tiling. Here we show, experimentally, how a desiccation crack pattern changes from being dominated by 90° joint angles, to 120° joint angles.

A method to model the effect of pre-existing cracks on P-wave velocity in rocks
Journal of Rock Mechanics and Geotechnical Engineering, 2020 Crack closure is one of the reasons inducing changes of P-wave velocity of rocks under compression. In this context, a method is proposed to investigate the relationships among P-wave velocity, pre-existing cracks, and confining pressure based on the ...
