TL;DR: A review of the development and the state of the art in dynamic testing techniques and dynamic mechanical behaviour of rock materials can be found in this article, where a detailed description of various dynamic mechanical properties (e.g., uniaxial and triaxial compressive strength, tensile strength, shear strength and fracture toughness) and corresponding fracture behaviour are discussed.

TL;DR: A detailed experimental procedure for the quantitative determination of mechanical properties and full-field strain measurement of rock material under dynamic loads was presented in this paper, where three kinds of testing methods, i.e., notched semi-circular bending, Brazilian disc, and uniaxial compression, were conducted using a split Hopkinson pressure bar (SHPB) system.

TL;DR: In this article, the authors used a micromechanical model to examine the intergranular and transgranular fracture properties of a marble and found that fracture toughness and surface roughness were dependent on loading rate.

TL;DR: In this paper, a tension and compression-shear damage model is developed, and then is implemented into the commercial software LS-DYNA as a user-defined material model, and the comparison between numerical results and an existing field test is conducted.

TL;DR: In this article, the Riedel-Hiermaier-Thoma (RHT) model in the LS-DYNA software was employed to assess the causes of the difficulties encountered in cut blasting.
