Optimizing the thermal gradient and the pulling speed in a thermoplastic pultrusion process of pet/e glass fibers using finite element method
(Savez inženjera metalurgije Srbije, Beograd, 2018)
A thermoplastic pultrusion process was examined using commercial fiber roving of PET/E glass, to determine the optimum pulling speed and optimal zonal temperatures. Finite element analysis predicted heat transfer through ...
Integrity assessment of vital beam components that enable conjoint operation of two bridge cranes
(Society for Structural Integrity and Life, Institute for Material Testing, 2018)
Vital components of the beam that enable conjoint operation of two bridge cranes are braces and threaded spindle. The beam connects two bridge cranes with overall lifting capacity of 500 t (2 x 250 t) and enables their ...
Application of raw volcanic rock found in etna valley as an adsorbent of chromates, arsenates and selenates
(Savez inženjera metalurgije Srbije, Beograd, 2018)
This paper aims to determine the potential of volcanic rock found in Etna valley as an adsorbent of heavy metals in anionic form (chromates, arsenates, and selenates). Characterization of the volcanic rock was done with ...
