Hydraulic fracturing is an efficient stimulation means for the exploitation of unconventional
oil/gas resources as well as geothermal energy. However, there are several issues for …

The Schmidt hammer provides a quick and inexpensive measure of surface hardness that is
widely used for estimating the mechanical properties of rock material. However, a number of …

The use of three artificial neural network (ANN)-based models for the prediction of
unconfined compressive strength (UCS) of granite using three non-destructive test …

Coral reef limestone at different depositional depths and facies differ remarkably on the
textural and mineralogical characteristics, owing to the complex sedimentary diagenesis. To …

Many attempts have been made to predict unconfined compressive strength (UCS) of rocks
using back-propagation (BP) artificial neural network (ANN). However, BP-ANN suffers from …

The uniaxial compressive strength (UCS) is one of the most important parameters for
judging the mechanical behaviour of rock mass in rock engineering design and excavation …

This paper reports the results of soft computing-based models correlating L and N-type
Schmidt hammer rebound numbers of rock. A data-independent database was compiled …

This study numerically investigates the influence of material heterogeneity on the strength
and deformation behavior and the associated microcracking process of a felsic crystalline …

This study investigated the correlations between mechanical properties and mineralogy of
granite using the digital image processing (DIP) and discrete element method (DEM). The …

The uniaxial compressive strength (UCS) is a vital rock geomechanical parameter widely
used in rock engineering projects such as tunnels, dams, and rock slope stability. Since the …
