Correlation between uniaxial compression strength and point load index for Irish Caledonian granites
, 2022 While the Uniaxial Compression Strength (UCS) test is the gold standard for determining the UCS of rock for geotechnical and mining applications, empirical correlations between UCS and other test measurements are useful in situations where intact cores are difficult to retrieve and/or the scope of UCS testing is constrained by budget.

Damage process of a fiber bundle with a strain gradient [PDF]
, 2008 We study the damage process of fiber bundles in a wedge-shape geometry which ensures a constant strain gradient. To obtain the wedge geometry we consider the three-point bending of a bar, which is modelled as two rigid blocks glued together by a thin ...
