Stanovení přetvárných charakteristik pískovce ultrazvukovou metodou : závěrečná zpráva
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.
Strength tests of sandstones from Bohemian Switzerland National Park (locality of Hřensko and Pravčická brána)
Živor, Roman
Simple compressive strength and cross-tensile strength (by Brazilian test) of sandstone samples from area of Bohemian Switzerland National Park were determined. Strength properties were found during three various conditions of the rock moisture – natural (laboratory), minimal and maximal rock moistures.
