The influence of printing orientation on the flexural strength of PA 12 specimens produced by SLS
(Science of Sintering, 2023)
This article aims to investigate the mechanical characteristics of specimens fabricated using Selective Laser Sintering technology. The research covers flexural specimens, produced by PA12 materials. CAD model dimensions ...
Bucket wheel failure caused by residual stresses in welded joints
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Cracks in the welded joints on the bucket wheel (BW) body of the bucket wheel excavator (BWE) SRs 1300 were discovered after merely 1800 h of operation. Investigations are carried out in order to detect the causes of cracks ...
Uticaj ograničenog deformisanja na nastanak žilavog loma korišćenjem kompletnog Gursonovog modela - numerička simulacija / Numerical simulation for studying constraint effect on ductile fracture initiation using complete Gurson model
(Univerzitet u Beogradu - Mašinski fakultet, Beograd, 2010)
Nastanak žilavog loma u zavarenim spojevima niskolegiranog čelika povišene čvrstoće je predviđen primenom mikromehaničkog kompletnog Gursonovog modela (CGM). Ograničeno deformisanje oko vrha prsline (eng. 'constraint') i ...
Helicopter Rotor Blade Shape Optimization Using NURBS for Airfoil Shape Parameterization
(AIP Conference Proceedings, 2009)
An introductory study of helicopter main rotor blade aerodynamic shape optimization problem is presented. Optimization process is carried out in compressible, viscous, quasi-steady fluid flow field of hovering rotor described ...
An analysis of the influence of weldment heterogeneity in ferrite-austenite welded structure
(Welding in the World, 2009)
An analysis of the influence of heterogeneity of the ferriteaustenite welded joint on its integrity has been performed. The Charpy specimens, with notch positioned in different regions of welded joint, have been tested ...
Thermal stress analysis of a fiber-epoxy composite material
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2011)
Paper presents stress calculation in the stationary temperature domain for a hybrid structure with standard epoxy-carbon fiber composite and metallic part, showing different thermal behavior. The thermal stress analysis ...
Neural network model for the condition assessment of hydro turbines
(University of Belgrade - Faculty of Mechanical Engineering, Belgrade, Serbia, 2022)
During regular operation, hydro turbine elements have complex operating conditions. In order to prevent major failures, among other common preventive measures, it is necessary to make a useful model of hydro turbine. ...
