IMAGE SYNTHESIS OF METAL FOAM MICRO-STRUCTURE WITH THE USE OF WANG TILES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
In this paper we present our recent work focused on the analysis of the abilities of Wang Tiles method and Automatic tile design method to synthesize the micro-structure of cellular materials, especially particular type ...
GEOMETRY AND MECHANICAL PROPERTIES OF A 3D-PRINTED TITANIUM MICROSTRUCTURE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
Construction applications sometimes require use of a material other than construction steel or concrete – mainly in cases, where strength to weight ratio needs to be considered. A suitable solution to this problem are ...
ASSESSMENT OF ADHESION BETWEEN MINERAL AGGREGATE AND BITUMINOUS BINDER USING DIGITAL IMAGE ANALYSIS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
This work presents how to assess a rate of adhesion between bituminous binder and mineral aggregate. Asphalt mixtures composed from grade bitumen 50/70, reference or modified with adhesion promoters based on amines, and ...
CHARACTERIZATION OF CEMENT-BASED COMPOSITE EXPOSED TO HIGH TEMPERATURES VIA ULTRASONIC PULSE METHOD
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
In this paper, the attention is paid to the investigation of the influence of high temperature acting on specimens made from specially designed cement-based composite. The experimental programme was carried out on six sets ...
STRENGTH OF COMPOSITE YARN UNDER BIAXIAL LOADING
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The present paper is concerned with two types of periodic unit cell of composite yarn with different geometry but the same material properties. Their macroscopic response under tensile and compressive loading in the ...
VALIDATION OF LINKED SIMULATION FOR FIRE-EXPOSED CONCRETE STRUCTURES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
This article presents linked computational approach for fire simulation and its effects on structure using adiabatic surface temperature. The simulation solves a weakly-linked problem, consisting of computational fluid ...
CONSTITUTIVE MODEL FOR TIMBER FRACTURE USED FOR FE SIMULATION OF LVL ARCH
(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 ...
RELATION BETWEEN STATIONARY AND MOVING PEDESTRIAN LOAD MODELS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The dynamic analysis of footbridges became common in recent years, but the approach to modelling pedestrian induced load is still inconsistent. This paper compares two different ways of modelling single pedestrian load. ...
WHICH FANS ARE THE BIGGEST ACCELERATION OF THE GRANDSTAND?
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The fans of AC Sparta Prague and SK Slavie Prague have been arguing about the fact whose fans support their team better since the end of 20th century. There have been made many experiments on the intensity of vibrations ...
MODELING OF UNDERGROUND STRUCTURES SUBJECTED TO EARTHQUAKE BY COMBINING 1D FREE-FIELD AND 2D PSEUDO-STATIC ANALYSES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)
The paper deals with the evaluation of tunnel construction subjected to earthquake using a pseudostatic analysis combined with the finite element method. The initial stage of calculation is concerned with the design of ...
