The uniaxial compressive strength (UCS) of rock is an essential property material in different relevant applications, such as slope, tunnel construction, and foundation. It takes enormous time effort to obtain the UCS values directly laboratory. Accordingly, indirect determination through conducting several index tests that are easy fast carry out interest importance. This study presents powerf...

Knowledge regarding the time-dependent behavior of rocks is essential to estimate long-term deformation and stability underground structures. The rock strength increases with increasing loading rate. However, rate dependence in postfailure regions under confining pressure remains unclear. In this study, triaxial compression tests were conducted on four types examine both peak regions. Results d...

[1] Pronounced rainfall gradients combined with spatially uniform exhumation of rocks at Quaternary timescales and uniform rock strength make the upper Marsyandi River valley in central Nepal a useful natural laboratory in which to explore variations in bedrock channel width. We focus on small catchments (0.6–12.4 km) along a more than tenfold gradient in monsoon rainfall. Rainfall data are gat...

Rock climbers perform repeated isometric forearm muscle contractions subjecting the vasculature to repeated ischaemia and distorted haemodynamic signals. This study investigated forearm vascular characteristics in rock climbers compared to healthy untrained controls. Eight climbers (CLIMB) (BMI; 22.3, s = 2.0 kg/m(2), isometric handgrip strength; 46, s = 8 kg) were compared against eight untrai...

A split Hopkinson pressure bar (SHPB) system with a special shape striker has been suggested as the test method by the International Society for Rock Mechanics (ISRM) to determine the dynamic characteristics of rock materials. In order to further verify this testing technique and microscopically reveal the dynamic responses of specimens in SHPB tests, a numerical SHPB test system was establishe...
