Mass minimization of an AFG Timoshenko cantilever beam with a large body placed eccentrically at the beam end
(Beograd : Srpsko društvo za mehaniku, 2021)
Shape optimization of an AFG Timoshenko cantilever beam of a variable cross-sectional
area, with a specified fundamental frequency, is considered. The cantilever beam has a finitedimensional
body placed eccentrically at ...
Assessment of integrity of pressure vessels for compressed air
(Institut za ispitivanje materijala, Beograd, 2021)
Fracture mechanics approach for structural integrity assessment is described in the case of pressure vessels for compressed air. The results of non-destructive testing indicated unacceptable defects on the vessels and set ...

(Elsevier, Amsterdam, 2021)
This paper provides in-depth knowledge about the evolved gas analysis interpretation via newly proposed semi-quantitative approach, arising from thermogravimetric analysis (TGA) - mass spectrometry (MS) coupled measurements, ...
Analysis of corrosion depth percentage on the inner bottom plates of aging bulk carriers with an aim to optimize corrosion margin
(Univ Zagreb Fac Mechanical Engineering & Naval Architecture, Zagreb, 2021)
To ensure the better structural integrity and maximum safety of bulk carriers in the ship design phase, an appropriate corrosion margin is introduced by the classification societies, which should enable the exploitation ...
Effects of high thermal loads produced by interaction of accelerated plasma with steel surfaces (100Cr6, 16MnCr5, 42CrMo4)
(Elsevier Science Sa, Lausanne, 2021)
Magnetoplasma compressor (MPC), a type of plasma accelerators, is used for treatment and alloying of steel samples: steel 100Cr6, steel 16MnCr5 and steel 42CrMo4. The high-speed plasma flow formed within the MPC, from ...
