HSLA Steel - Simulation of Fatigue
(Springer, 2020)
In present paper, based on the results of the experimental study of the behaviour of the samples made of a HSLA steel, in the form of round smooth specimens (RSS) under LCF conditions (with controlled and completely ...
Linearno toplotno širenje građevinskog kamena poreklom iz plutonskih magmatskih kompleksa Eksterne vardarske zone Srbije / Linear thermal expansion of the building stone from plutonic massifs of the Vardar zone of Serbia
(Savez inženjera i tehničara Srbije, Beograd, 2020)
Toplotna svojstva građevinskog kamena koji se koristi za oblaganje vertikalnih i horizontalnih površina građevinskih objekata, naročito u eksterijeru, imaju veliki značaj za stabilnost i vek trajanja, ali i estetska svojstva ...
Numerical model of fluid-structure interaction for water tower analysis of vibrations
(Institut za ispitivanje materijala, BeogradDruštvo za integritet i vek konstrukcija (DIVK), 2020)
This paper deals with the aspects of vibration analysis of 3D numerical water tower models with the explicitly generated 3D finite element (FE) solid fluid model that simulates the fluid-structure interaction (FSI). The ...
Nonlinear Dynamics as a Tool in Selection of Working Conditions for Radial Ball Bearing
(Springer, 2020)
This paper contains elements of a comprehensive research devoted to the dynamic behavior of radial ball bearings in real working conditions. The general motivation for this topic comes from the requirements for high ...
Tie-rods of the bucket wheel excavator slewing superstructure: A study of the eye plate stress state
(Elsevier Sci Ltd, Oxford, 2020)
Tie-rods of the bucket wheel and counterweight booms are vital parts of the bucket wheel excavator slewing superstructure. This paper is dedicated to the problem of identifying the stress state of the critical cross-section ...
A Theoretical Model for Vibro-Impact Dynamics of Spur Gears with Tooth Flanks Wear
(Springer Nature, 2020)
The main performance of involute gears operation leads to the appearance of nonlinear dynamic behavior and impact. In this chapter the influence of mild wear of the tooth flanks of gears without machine finishing and surface ...
What is the most relevant method for water absorption determination in ceramic tiles produced by illitic-kaolinitic clays? The mystery behind the gresification diagram
(Sociedad Espanola de Ceramica y Vidrio, 2020)
This study presents the 51 mixtures of ceramic clays characterized by using XRF, XRD, granulometry, and dilatometry analyses. After firing in a 1000-1250 °C range, water absorption (WA) according to EN standards by boiling ...
Failure analysis of ATR 72 tow bar–opportunity for re-design for inspection
(10th EASN Virtual International Conference on Innovation in Aviation & Space to the Satisfaction of the European Citizens, 2020)
The safe towing of aircraft is an important part in aviation security. Failures during the towing and parking
related operations are not so rare due to bad working circumstance, human error, etc. Tow bars are simple
but ...
Imobilizacija teških metalnih jona Zn2+, Ni2+, Pb2+ i Cu2+ u strukturi materijala na bazi cementa / Immobilization of heavy metal ions Zn2+, Ni2+, Pb2+ and Cu2+ in the structure of cement-based materials
(Inženjersko društvo za koroziju, Beograd, 2020)
Prirodni zeolit i bentonit korišćeni su kao mineralni dodaci u mešavinskom dizajnu ekološki sigurnih građevinskih materijala na bazi cementa. Ispitane su adsorptivne sposobnosti ove dve glinene sirovine, tj. njihov afinitet ...
Bucket wheel excavators_Dynamic response as a criterion for validation of the total number of buckets
(Engineering Structures, 2020)
An original method for validation of the number of buckets on the working device of a bucket wheel excavator based on the dynamic response of its slewing superstructure (SS) is presented. A set of 16 seemingly acceptable ...
