TL;DR: In this article, an experimental study of stress wave propagation across filled rock joints has been carried out using a modified Split Hopkinson Pressure Bar (SHPB) apparatus, where two granitic bars cored from a rock site were used as the incident and transmitter pressure bars in the SHPB tests, while a sand layer of different widths and water contents sandwiched between the two bars was adopted to simulate the filled joint.

TL;DR: In this paper, a virtual wave source (VWS) is proposed to take into account the wave reflections between the joints, which can be effectively applied to analyze longitudinal wave propagation through discontinuous media with parallel joints.

TL;DR: Based on the conservation of momentum at the wave fronts and the displacement discontinuity method, quantitative analysis for the interaction between obliquely incident P- or S-blast wave and a linear elastic rock joint is carried out in this article, so as to deduce a wave propagation equation.

TL;DR: In this article, the authors investigated the influence of extreme temperatures (from 25° to 1000°C) followed by two cooling methods (both rapid and slow) on the mechanical behaviour of clay-rich Hawkesbury sandstone under uniaxial conditions.

TL;DR: A review of foam-based fluid fracturing, its merits and demerits and the associated environmental footprint can be found in this article, where the authors discuss the properties of injecting foam, including its rheology and viscosity, are important for the fracturing process.
