The mechanical sciences are old and venerable. But age does not protect from stupidity.
The Cremona-plan and the theorem of the parallelogram of forces in their seniority have …

Stress waves propagating through multiple parallel fractures are attenuated (and slowed)
due to multiple wave reflections and transmissions at the fractures. This paper presents a …

Wave attenuation across fractured rock masses is a great concern of rock engineers to
assess the safety of underground structures in and on rocks under dynamic loads. Due to …

Rock joints are often filled with weak medium, for example, saturated clay or sand, of
viscoelastic nature. Their effects on wave propagation can be modelled as displacement …

Underground explosion during, eg, blasting excavation, could generate shock waves, which
propagate in surrounding rock mass and might result in damage or destruction of …

This paper investigates the details of reflection, transmission, and conversion of plane
waves incident upon a fracture at arbitrary angles. The elastic compliance of fractures that is …

Drilling and blasting is a major technology in mining since it is necessary for the initial
breakage of rock masses in mining. Only a fraction of the explosive energy is efficiently …

Due to the presence of joints, waves are greatly attenuated when propagating across rock
masses. Zhu et al.(2011)(Normally incident wave propagation across a joint set with virtual …

Stress wave attenuation across fractured rock masses is a great concern of underground
structure safety. When the wave amplitude is large, fractures experience nonlinear …

This paper describes ultrasonic measurements of normal and tangential stiffnesses of the
contacting interface between polished aluminum blocks subjected to nominal contact …
