COMPARING MORI-TANAKA METHOD AND FIRST-ORDER HOMOGENIZATION SCHEME IN THE VISCOELASTIC MODELING OF UNIDIRECTIONAL FIBROUS COMPOSITES
Autor: Valentová, Soňa; Šejnoha, Michal; Vorel, Jan
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)A comparative study of the viscous response of polymer matrix based fibrous composites predicted by the Mori-Tanaka method and finite element simulations based on the 1st order homogenization theory is presented. Aligned ... -
HOMOGENIZATION OF UNREINFORCED OLD MASONRY WALL COMPARISON OF SCALAR ISOTROPIC AND ORTHOTROPIC DAMAGE MODELS
Autor: Bernardo, Vasco; Krejčí, Tomáš; Koudelka, Tomáš; Šejnoha, Michal
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)Masonry is a heterogeneous composite material made of bricks bonded by a mortar matrix. Modeling such a material on macroscale typically calls for homogenization adopting a suitable constitutive model capable of capturing ... -
INFLUENCE OF MATERIAL DAMPING ON THE RESPONSE OF UNDERGROUND STRUCTURES SUBJECTED TO EARTHQUAKE
Autor: Pavelcová, Veronika; Poklopová, Tereza; Šejnoha, Michal; Janda, Tomáš
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)The paper describes a finite element simulation of the response of a real underground structure subjected to earthquake using GEO5 FEM program. It concentrates on the influence of material damping with respect to a specific ... -
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 ...
