WANG TILES LOCAL TILINGS CREATED BY MERGING EDGE-COMPATIBLE FINITE ELEMENT MESHES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
In this contribution, we present the concept of Wang Tiles as a surrogate of the periodic unit cell method (PUC) for modelling of materials with heterogeneous microstructures and for synthesis of micro-mechanical fields. ...
METHODOLOGY FOR MEASURING THE SHEAR STRESS OF PLASTERBOARDS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
Plasterboards have to meet many requirements for certification. The mechanical properties of itself plasterboard are one of them. The important mechanical property of the plasterboard is the shear strength perpendicular ...
THE OCCURRENCE OF SYNCHRONIZED JUMPING CROWD AT SPORTS STADIUMS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
Since the age of the Rome Empire, people have been going for fun at the stadiums. Today, important reasons for visiting the stadium are sport games or cultural performances. The text is about occurrence of specific types ...
ASSESSMENT OF 2D-DIC STOCHASTIC PATTERNS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
Cost of experimental testing of materials and structures subjected to mechanical loading often constitutes a significant portion of a project budget. Therefore a collection of data in a maximum possible amount is desirable. ...
VARIATIONALLY-BASED EFFECTIVE DYNAMIC THICKNESS FOR LAMINATED GLASS BEAMS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
Laminated glass, consisting of glass layers connected with transparent foils, has found its applications in civil, automotive, or marine engineering. Due to a high contrast in layer properties, mechanical response of ...
PERFORMANCE OF CEMENT COMPOSITES REINFORCED WITH SURFACE-MODIFIED POLYPROPYLENE MICRO- AND MACRO-FIBERS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
This paper focuses on the mechanical properties investigation of cement pastes reinforced with surface treated polymer fibers. The cement matrix was composed of Portland cement (CEM I 42.5 R, w/c ratio equal to 0.4). Two ...
COUPLED SIMULATION FOR FIRE-EXPOSED STRUCTURES USING CFD AND THERMO-MECHANICAL MODELS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
Fire resistance of buildings is based on fire tests in furnaces with gas burners. However, the tests are very expensive and time consuming. This article presents a coupled simulation of an element loaded by a force and a ...
PULLOUT BEHAVIOR OF OXYGEN PLASMA TREATED POLYMER FIBERS FROM CEMENT MATRIX
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
The aim of this work is to describe bonding properties between surface treated polymer fibers and a cement matrix. In order to increase an interaction between the matrix and fiber surfaces, two fiber types having approx. ...
EVALUATION OF EFFECTIVE PROPERTIES OF BASALT TEXTILE REINFORCED CERAMIC MATRIX COMPOSITES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
The present paper is concerned with the analysis of a ceramic matrix composite, more specifically the plain weave textile fabric composite made of basalt fibers embedded into the pyrolyzed polysiloxane matrix. Attention ...
HYDRATION PROCESS AND MECHANICAL PROPERTIES OF CEMENT PASTE WITH RECYCLED CONCRETE POWDER AND SILICA SAND POWDER
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2017)
Recycled concrete powder (RCP) mostly consisting of cement paste could be reused as partial cement replacement. The aim of this paper is to compare hydration and mechanical properties of RCP and two types of silica sand ...
