Measurement of mode I and mode II rock dynamic fracture toughness with cracked straight through flattened Brazilian disc impacted by split Hopkinson pressure bar (2011, methodology): “The load P(t) used in finite element computation is an average of PL(t) and PR(t) with consideration of time shift for PR(t) with respect to PL(t), which is caused by stress wave traveling through the specimen [14,15].”
Effects of Thermal Treatment on Tensile Strength of Laurentian Granite Using Brazilian Test (2015, background): “failure often occurs in rock masses (Wang et al. 2009).”
A Review of Dynamic Experimental Techniques and Mechanical Behaviour of Rock Materials (2014, methodology): “To prevent failure near the loading points, several improvements were introduced, namely using steel bearing bars (Gomez et al. 2001), using curved anvils (Dai et al. 2010c; Grantham et al. 2004) and the flattened BD method (Wang et al. 2009).”
