Since concentrating on geotechnical applications the accompanied numerical ... -
QCT/FEA analyses of palateless splinted and unsplinted maxillary all-on-4 systems
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)The goal of the presented study was to determine the viability of using splinted and unsplinted maxillary implant-supported overdentures. The main physical quantity used to evaluate their differences was compressive stress ... -
Measurement of tensile properties of selected rovings
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)This article is focused on measuring the tensile properties of chosen fibre materials, such as flax, alkali resistant glass or viscose. All selected materials were tested both pure and impregnated using epoxy resin. In ... -
The concept of fractured rock-mass modeling using DFN-based statistical volume elements
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)The overall mechanical response of a fractured rock mass is, to a large extent, affected by naturally occurring fractures that exhibit sizes from millimeters to kilometers. Thus, in analysis of underground structures, such ... -
Transforming point cloud data into 3D BIM models: a case study on slabs
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)We explore the automatized transition of point cloud data into a Building Information Model (BIM), an essential task for reconstructions, demolition plans, or auditing. In this study, we use point cloud data generated by ... -
Numerical modeling of concrete beams subjected to partial wetting and drying cycles
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Concrete structures are commonly subjected to cycles of wetting and drying, which can have a significant impact on their behavior. However, experimental data on the effects of wetting and drying on concrete beams are scarce. ... -
Properties of cement screeds using recycled fine aggregates with respect to cement percentage
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)This article deals with the effect of 100% replacement of natural aggregate by recycled aggregate and at the same time the effect of cement percentage on the observed properties of cement screeds. For these purposes, ... -
Fractional order models of viscoelastic polymeric solids undergoing large deformations
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)We present a fractional order model for nonlinear visco-hyperelastic solids taking into account large deformations. A three-field form of the Hu-Washizu principle is introduced to create a stable finite element method in ... -
Dynamic behavior of a cable-stayed footbridge depending on the calculation accuracy
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Footbridges are analyzed in terms of dynamic response for pedestrian comfort. This problem is solved mainly on light and at the same time rigid constructions, which are easily oscillated by pedestrian load. It is often ... -
Image-based random fields in numerical modeling of heterogeneous materials
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Modeling of spatial variability using random fields is nowadays standard in computational modeling of heterogeneous materials. The only difficulty remains in determining the input parameters of the random field in order ... -
Effect of geometry on homogenised properties of selected auxetic metamaterials
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Our study investigates the influence of geometrical parameters of two types of auxetic metamaterials on their effective properties. In particular, we focus on three-dimensional lattice structures, which we represent with ... -
Experimental of verification of alternative hydraulic binders flexural and compressive strength
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)The paper deals with the investigation of alternative binders, namely the two available samples N6 and N7 with comparison from the reference sample CEM I 42.5R. Both testing binders are provided by company Destro. It is a ... -
Validation of geotechnical laboratory tests data obtained from various sources
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Data validation is a critical step in every data analysis. It is a well-known fact that the results of any data analysis are directly dependent on the input values. This paper works with a worldwide database of laboratory ... -
Reconstruction of concrete morphology using deep learning
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)In this contribution, the concrete morphology is reconstructed with a simple algorithm selecting a pixel value based on the small set of surrounding pixels. A deep neural network (DNN) is used as a classifier, and the ... -
Impact of bolt positioning on the stiffness of angular support brackets
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2024)Bolts and screws are usually preferred over other joining techniques when assembly and disassembly operations are required. However, they add extra weight to the system, so it is essential to reduce their size and weight ... -
