Fracture parameters of natural and artificial sandstone: experiment vs. numerical model
Pail T., Štafa M., Šimonová H., Frantík P., Keršner Z.
pages 97 - +4p., full text

The results of fracture experiments and numerical model with sandstone specimens are presented in this paper. The aim is the comparison of selected mechanical/fracture parameter values of Mšeno sandstone specimens and artificial sandstone prepared from quartz sand and geopolymer matrix. The relative values of elasticity modulus/stiffness and fracture energy/work of fracture are introduced using fracture test results as well as results of numerical simulation by the simple bending fracture model (SimBeFraM software).
