Živor, Roman ; Lokajíček, Tomáš ; Filler, Vlastimil
Dynamic deformational characteristics – modulus of elasticity, modulus of rigidity and Poisson‘s ratio were determined by the laboratory ultrasonic pulse method on samples of Cretaceous sandstone from Prague underground tunnelling. The characteristics were calculated from of P and S wave velocities found during ultrasonic propagation of rock samples.
