    • MODELLING OF TIME-DEPENDENT BEHAVIOUR OF PARTICULATE THERMOSET POLYMERS 

      Autor: Vozáb, Jan; Vorel, Jan
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      A preliminary study of a numerical model describing the behaviour of polymer-based composites is presented. The numerical model consists of three main parts. The first is the microplane M4 model, which is the main part of ...

    • SIZE EFFECT ON THE ULTIMATE DRYING SHRINKAGE OF CEMENT MORTAR: 1-YEAR EXPERIMENT AND NUMERICAL MODELING 

      Autor: Dohnalová, Lenka; Havlásek, Petr; Šmilauer, Vít; Reiterman, Pavel; Davidová, Vendula
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      The magnitude and time evolution of shrinkage are influenced by numerous factors which are implemented in the design codes often in a different way. The time-dependent behavior of concrete in structures sensitive to creep ...

    • PLASMA MODIFICATION OF MICROFIBERS - APPLICATION TO LIGHTWEIGHT CEMENT COMPOSITE CONTAINING RECYCLED CONCRETE 

      Autor: Ďureje, Jakub; Prošek, Zdeněk; Trejbal, Jan; Tesárek, Pavel; Potocký, Štěpán
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      The article deals with the optimalization of composition for reinforced lightweight cement composite containing micronized recycled concrete, which will be used to produce masonry blocks. The composite material is reinforced ...

    • FINITE ELEMENT IMPLEMENTATION OF GEOMETRICALLY NONLINEAR CONTACT 

      Autor: Faltus, Ondřej; Horák, Martin
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)
      The OOFEM finite element software has been recently updated to include contact algorithms for small strain applications. In this work, we attempt to extend the contact algorithms to large strain problems. Reviewing the ...
