Precisely understanding the dynamic mechanical properties and failure modes of rocks
subjected to true triaxial stress state (σ 1> σ 2> σ 3, where σ 1, σ 2, and σ 3 are the major …

Accurate prediction of compressive strength of rocks relies on the rate-dependent behaviors
of rocks, and correlation among the geometrical, physical, and mechanical properties of …

Rock joints are prone to open and fail when subject to severe dynamic extension, which
might result in spalling of surrounding rock and collapse of underground openings …

Research on rock fracture behavior is usually limited to static mixed mode I/II fracture and
static or dynamic mode I fracture. In this study, the notched semi-circular bend (NSCB) …

Comprehensive understanding related to the dynamic responses of the composite materials
