    • MICROSCOPIC FEATURES OF CEMENT PASTE MODIFIED BY FINE PERLITE 

      Autor: Hrbek, Vladimír; Koudelková, Veronika; Padevět, Pavel; Šašek, Petr
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      The use of waste material and replacement of binder element in cementitious composites is in focus of material development. Perlite in the construction industry is usually used in form of lightweight aggregate enhancing ...

    • MODELING OF ANISOTROPIC GROWTH AND RESIDUAL STRESSES IN ARTERIAL WALLS 

      Autor: Zahn, Anna; Balzani, Daniel
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      Based on the multiplicative decomposition of the deformation gradient, a local formulation for anisotropic growth in soft biological tissues is formulated by connecting the growth tensor to the main anisotropy directions. ...

    • NUMERICAL DISCRETISATION OF BUILT STRUCTURES ASSUMPTION AND REALITY 

      Autor: Gutermann, Marc; Schröder, Carsten
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      The second half of the 20th century was affected by the introduction of electronic data processing. The numerical methods appeared to be capable of solving every engineering problem. However, dealing with real problems, ...

    • NUMERICAL PREDICTIONS AND MECHANICAL TESTING OF BRAIDED COMPOSITE STRUCTURES UTILISING DIGITAL IMAGE CORRELATION 

      Autor: Pitz, Emil; Miron, Matei-Constantin; Kállai, Imre; Major, Zoltán
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      The current paper is describing the implementation of a multiscale numerical model for prediction of stiffness and strength in braided composites. The model is validated by experimental testing of single-layer braided tubes ...

    • PARAMETERS AFFECTING THE STRUCTURAL ANALYSIS OF A TUNNEL STRUCTURE EXPOSED TO FIRE 

      Autor: Pouran, Omid; Harte, Reinhard; Peter, Carsten
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      Behaviour of cut-and-cover tunnels exposed to fire should be analysed by using a realistic structural model that takes account of mechanical and thermal effects on the structure. This has been performed with the aid of ...

    • PERFORMANCE OF STEEL FIBER REINFORCED CONCRETE – COMPARABILITY OF TESTS ACCORDING TO DAFSTB-GUIDELINE "STAHLFASERBETON" AND EN 14651 

      Autor: Anders, Steffen; Schovenberg, Melanie
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      For the determination of the performance of steel-fiber reinforced concrete (SFRC), the post-peak flexural strengths are used. In different national and European standards, different test-setups are defined, resulting in ...

    • RIGHTING OF CHINESE MITTEN CRABS (ERIOCHEIR SINENSIS) AND THEIR MODELS 

      Autor: Riphaus, Tobias; Hoffmann, Florian; Labisch, Susanna
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      The usage of unmanned underwater vehicles for marine tasks is continuously growing and bioinspired stabilizing systems shall help them to gain and keep a stable position during work. Therefore the righting maneuver of E. ...

    • SEMI–AUTOMATED ASSESSMENT OF MICROMECHANICAL PROPERTIES OF THE METAL FOAMS ON THE CELL-WALL LEVEL 

      Autor: Krčmářová, Nela; Šleichrt, Jan; Doktor, Tomáš; Kytýř, Daniel; Jiroušek, Ondřej
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      Metal foams are innovative porous material used for wide range of application such as deformation energy or sound absorption, filter material, or microbiological incubation carrier. To predict mechanical properties of the ...

    • SHEARING TESTS APPLIED TO PANTOGRAPHIC STRUCTURES 

      Autor: Ganzosch, Gregor; dell’Isola, Francesco; Turco, Emilio; Lekszycki, Tomasz; Müller, Wolfgang H.
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      With the advancements in 3D printing technology, rapid manufacturing of fabric materials with complex geometries became possible. By exploiting this technique, different materials with different structures have been developed ...

    • UHPC SANDWICH STRUCTURES WITH COMPOSITE COATING UNDER COMPRESSIVE LOAD 

      Autor: Markowski, Jan; Lohaus, Ludger
      (České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
      Ultra-high-performance concrete (UHPC) sandwich structures with composite coating serve as multipurpose load-bearing elements. The UHPC’s extraordinary compressive strength is used in a multi-material construction element, ...

    • VALIDATION AND IMPLEMENTATION OF FAILURE PARAMETERS IN INTEGRATED SIMULATIONS FOR SHORT FIBRE REINFORCED POLYPROPYLENE
