Tensile properties of polypropylene additively manufactured by FDM
(Society for Structural Integrity and LifeIMS Institute, 2022)
Polypropylene (PP) is an extensively studied and tested environment-friendly polymer, whose applications range from product packaging in the food industry to biomedical applications. It is a non-toxic, lightweight material, ...
Optimisation of numerical models of welded joints with multiple defect combinations
(ECF23, European Conference on Fracture 2022, Procedia Structural Integrity, 2022)
Research of expendable turbojet tubular combustion chamber
(Sage Publications Ltd, London, 2022)
This paper presents research related to the tubular combustion chamber of an expendable turbojet. Although annular combustors are dominant at present, tubular combustors are still attractive because they are simpler to ...
Loading Rate Effects on MOE and MOR Distributions in Testing of Small Clear Beech Wood Specimens
(North Carolina State Univ Dept Wood & Paper Sci, Raleigh, 2022)
Distributions of the modulus of elasticity (MOE) and modulus of rupture (MOR) were characterized at three loading rates for small clear beech specimens in static bending. The correlation between MOE and MOR for all three ...
Structural integrity and life assessment of oil drilling rig pipes using analytical method
(Institut za ispitivanje materijala, Beograd, 2022)
Structural integrity and life assessment of oil rig pipes using analytical method is presented and applied to an oil drilling rig pipe. The new concept based on risk evaluation according to probability and consequence of ...
Experimental and numerical stress and strain analysis of the boiler reversing chamber tube plate
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
Boilers are one of the most used units for both heat generation plants and industry systems. Their operation is subjected to different working loads and maintenance requirements. Exploitation experience points out critical ...
Thermo-mechanical analysis of linear welding stage in friction stir welding influence of welding parameters
(Univerzitet u Beogradu - Institut za nuklearne nauke Vinča, Beograd, 2022)
The influence of friction stir welding parameters on thermo-mechanical behav-ior of the material during welding is analyzed. An aluminum alloy is considered (Al 2024 T351), and different rotating and welding speeds are ...
Structural Integrity Analysis of a Kaplan Turbine Cover
(Elsevier Science Bv, Amsterdam, 2022)
During recent revitalization of Kaplan turbine aggregate made of structural steel St 3 (GOST standard), experimental investigation was performed. Base metal and welded joints were tested by non-destructive methods (NDT), ...
Fatigue crack growth in locking compression plates
(Elsevier Sci Ltd, Oxford, 2022)
Fatigue crack growth in orthopaedic locking compression plates (LCP), under four-point bending, has been simulated by the extended finite element method (xFEM) to assess LCP optimal geometry in respect to remaining life. ...
Ion Channel Modeling beyond State of the Art: A Comparison with a System Theory-Based Model of the Shaker-Related Voltage-Gated Potassium Channel Kv1.1
(MDPI, Basel, 2022)
The mathematical modeling of ion channel kinetics is an important tool for studying the electrophysiological mechanisms of the nerves, heart, or cancer, from a single cell to an organ. Common approaches use either a ...
