Finite element modelling of creep process - steady state stresses and strains
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Finite element modelling of steady state creep process has been described. Using an analogy of visco-plastic problem with a described procedure, the finite element method has been used to calculate steady state stresses ...
Modeling of the buckstay system of membrane walls in watertube boiler construction
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Membrane walls are very important structural parts of water-tube boiler construction. Based on their specific geometry, one special type of finite element was defined to help model the global boiler construction. That is ...
Uncertainty evaluation of the conducted emission measurements
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2013)
For the evaluation of measurement uncertainty in measuring the conduction emission, in this paper we propose a new model which uses mixed distribution. Evaluation of probability density function for the measurand has been ...
Isogeometric bending analysis of composite plates based on a higher-order shear deformation theory
(Korean Soc Mechanical Engineers, Seoul, 2014)
This research paper presents an isogeometric plate finite element formulation for analysis of thick composite plates. Isogeometric finite element method which is based on non-uniform rational B-splines (NURBS) basis ...
Numerical simulation of fatigue crack propagation in friction stir welded joint made of Al 2024-T351 alloy
(Pergamon-Elsevier Science Ltd, Oxford, 2015)
In this work, fatigue crack propagation in thin-walled aluminium alloy structure with two friction stir welded T joints has been simulated numerically. Crack propagation in stiffened part of the structure between two ...
The performance of pip-cascade controler in hvac system
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Primitive controllers used in the early version for HVAC systems, like the on-off (Bang-Bang) controller, are inefficient, inaccurate, unstable, and suffer from high-level mechanical wear. On the other hand, other controllers ...
Impact of choice of stabilized hysteresis loop on the end result of investigation of high-strength low-alloy (hsla) steel on low cycle fatigue
(Faculty of Metallurgy, 2014)
High strength low-alloy steel under low cycle fatigue at a certain level of strain controlled achieve stabilized condition. During the fatigue loading stabilized hysteresis loop is determined, which typical cycle of ...
Determining the theoretical reliability function of thermal power system using simple and complex weibull distribution
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The main subject of this paper is the representation of the probabilistic technique for thermal power system reliability assessment. Exploitation research of the reliability of the fossil fuel power plant system has defined ...
Thermomechanics of soft inelastics bodies with application to asphalt behavior
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
Thermomechanical behavior of hot mix asphalt (HMA) is considered. Its highly irregular microstructure is covered by the hierarchical approach. A brief survey of endochronic thermodynamics precedes constitutive consideration. ...
Influence of friction stir welding parameters on properties of 2024 t3 aluminium alloy joints
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2014)
The aim of this work is to analyse the process of friction stir welding (FSW) of 3 mm thick aluminium plates made of high strength aluminium alloy - 2024 T3, as well as to assess the mechanical properties of the produced ...
