Analysis of tunnel excavation based on linear DFN-FEM modelling
Autor: Lebeda, Martin; Kabele, Petr
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)Simulations of tunnel excavations have to take into account the natural occurrence of joints and faults in the surrounding rock mass, which dominantly control its mechanical response. In this paper, we present work in ... -
COMPARISON OF FAILURE CRITERIA FOR WOOD IN TENSILE-SHEAR STRESS STATE
Autor: Šmídová, Eliška; Kabele, Petr
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)An orthotropic failure criterion enhancing the Lourenco's criterion by a shear strength multiplier and a maximum shear strength upper bound has been recently proposed and validated for timber under tensile and shear loading ... -
CONSTITUTIVE MODEL FOR TIMBER FRACTURE USED FOR FE SIMULATION OF LVL ARCH
Autor: Šmídová, Eliška; Kabele, Petr
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)Non-linear finite element simulation of four-point bending test of a small-size arch is described in this paper. The arch of 780mm span is made of Yellow Poplar (Liriodendron tulipifera) laminated veneer lumber (LVL) and ... -
Finite element simulation of shear and compact tension tests on timber
Autor: Šmídová, Eliška; Kabele, Petr
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)The non-linear finite element simulation of the ASTM shear and pre-stressed compact tension tests was conducted. Tested specimens were cut from the glued laminated timber made of European spruce (Picea abies) with the ... -
RESPONSE AND DAMAGE EVOLUTION OF SINGLE EDGE NOTCHED TIMBER BEAMS UNDER THREE-POINT BENDING
Autor: Šmídová, Eliška; Kabele, Petr; Šejnoha, Michal
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)Two groups of small-size single edge notched beams (SENB) made of European spruce (Picea abies) were tested in three-point bending (3PB) until failure under displacement control. The first group comprised of eight solid ... -
The effect of sampling volume size on the apparent stiffness of jointed rock mass
Autor: Lebeda, Martin; Kabele, Petr
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Overall mechanical properties of a jointed rock mass are strongly affected by discontinuities – fractures – that naturally occur in rocks. Stochastically-generated discrete fracture network (DFN) modeling, which uses a ...
