Coupled static-dynamic tests were carried out on notched semi-circular bend (NSCB)
granitic specimens using a modified split Hopkinson pressure bar (SHPB) device, to …

Understanding the inconsistent rock fracture toughness (K Ic) measurement results from
different test specimen geometries helps provide suitable fracture parameters for …

In this study, the cracked straight through Brazilian disc (CSTBD) specimen was applied to
study the I/II mixed mode static fracture of diorite. The fracture load and fracture toughness …

Using ring-shape specimens containing two aligned cracks on the internal surface of the
ring, two test configurations subjected to tensile or compressive loads namely (i) …

Abstract Machine Learning (ML) method is widely used in engineering applications such as
fracture mechanics. In this study, twenty different ML algorithms were employed and …

Rock fracture after high temperature is always a hot topic in the field of rock engineering.
However, the mixed mode I/III fracture characteristics of thermal-treated rocks have rarely …

The semi-circular bend (SCB) method suggested by International Society for Rock
Mechanics (ISRM) is demonstrated to yield much conservative mode I fracture toughness. A …

The destruction and fracture failure of heat-treated rock structures have been major issues in
the underground engineering, such as disposal of highly radioactive nuclear waste, deep …

Abstract The International Society for Rock Mechanics has suggested three chevron notched
specimens (CB, SR and CCNBD) to measure mode I fracture toughness of rocks; however …

Prediction of mode I fracture toughness (K IC) of rock is of significant importance in rock
engineering analyses. In this study, linear multiple regression (LMR) and gene expression …
