PERFORMANCE EVALUATION OF DIFFERENT LINEAR EQUATION SOLVERS FOR SOLVING NONLINEAR FE PROBLEMS ON MULTICORE ARCHITECTURES
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)The aim of this paper is to evaluate the performance of existing parallel linear equation solvers to solving large-scale, nonlinear finite element analysis problems on systems with distributed memory. The parallel approach ... -
BOND CONNECTIONS OF HIGH PERFORMANCE CONCRETE (HPC) AND STEEL: "EXPERIMENTAL VERIFICATION OF SELECTION GLUED FOR TWO DIFFERENT SURFACES OF STEEL"
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)This article deals with the test of selected adhesives for glued connection of high performance concrete and steel plates with various surface treatments. Results of this experiment can be used as a basis for the possible ... -
BAYESIAN INFERENCE OF HETEROGENEOUS VISCOPLASTIC MATERIAL PARAMETERS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)Modelling of heterogeneous materials based on randomness of model input parameters involves parameter identification which is focused on solving a stochastic inversion problem. It can be formulated as a search for probabilistic ... -
COMPARISON OF DRYING SHRINKAGE AND DRYING CREEP KINETICS IN CONCRETE
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)The aim of this paper is to show and compare the time evolution of drying shrinkage and drying creep in concrete from three different perspectives. The first one analyzes the basic equations defined in the most common ... -
EFFECT OF VISCOUS DAMPING IN NUMERICAL CALCULATION OF CABLE-MEMBRANE STRUCTURES BY THE METHOD OF DYNAMIC RELAXATION
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)The aim of this article is to assess the speed of convergence of numerical calculation of cable-membrane structures using dynamic relaxation method in the process of finding critical damping pre-calculated on undamped ... -
ISOGEOMETRIC BEAM ELEMENT EXTENDED FOR GRIDSHELL ANALYSIS
(České vysoké učení technické v PrazeCzech Technical University in Prague, 2018)The design of gridshell structures is a complicated process, as the resulting shape of structure depends on initial undeformed grid geometry as well as on the history of boundary conditions used to form the final structure. ...
