Load transfer mechanism of concrete screws
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2022)Even though the market and development for concrete screws has been increasingly rising in recent years, the load transfer mechanism of concrete screws has not yet been fully investigated. Therefore, different tests of ... -
Local defect formation in short glass fibre reinforced polymers – micro-mechanical simulations and interrupted in-situ experiments
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2023)Discontinuous fibre reinforced polymers are widely used in various industry sectors and often replace conventional materials, due to lower production costs and their lightweight structure. For improvement of the component ... -
Local Magnetohydrodynamic Characteristics of the Plasma Stream generated by MPC
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2013)This paper investigates the spatial distributions of electrical current which flows inside the plasma stream generated by a magnetoplasma compressor (MPC). Two different modes of MPC operation with different gas supply ... -
LOCAL MECHANICAL PROPERTIES OF ATMOSPHERIC SPRAYED MOLYBDENUM COATINGS DEPOSITED WITH CASCADED PLASMA TORCH
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)Increasing interest for industrial use of thermally sprayed coatings leads to development in most thermal spraying technologies, including atmospheric plasma spraying (APS). The latest cascaded torch SinplexPro from Oerlikon ... -
LOCAL NANO-MECHANICAL PROPERTIES OF CROSS-LINKED POLYBUTYLENE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)Cross-linking is a process in which polymer chains are associated through chemical bonds. The cross-linking level can be adjusted by the irradiation dosage and often by means of a cross-linking booster. The polymer additional ... -
LOCAL VELOCITY PROFILES MEASURED BY PIV IN AN VESSEL AGITATED BY RUSHTON TURBINE

The experiments were carried out in a fully baffled cylindrical flat bottom vessel 300 ... -
LOCALIZATION ANALYSIS OF AN ORTHOTROPIC MULTI-SURFACE PLASTICITY MODEL UNDER UNIAXIAL STRESS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2020)Numerical simulations of masonry structures are often based on continuum macromodelling approaches that need constitutive laws able to phenomenologically reproduce the behavior of the material. To capture the deformation ... -
LOCALIZATION ANALYSIS OF DAMAGE FOR ONE-DIMENSIONAL PERIDYNAMIC MODEL
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2021)Peridynamics is a recently developed extension of continuum mechanics, which replaces the traditional concept of stress by force interactions between material points at a finite distance. The peridynamic continuum is thus ... -
