Assessing the forest management in the Novi Pazar region (Southwest Serbia)
(FRESENIUS ENVIRONMENTAL BULLETIN, 2022)
To address the question of weather stands are managed sustainably in the Novi Pazar region (Southwest Serbia), this study compares the quantity of standing wood biomass in the Debeljak-Medenovac unit at the beginning and ...
Failure analysis of welded joint with multiple defects by extended Finite Element Method and Engineering Critical Analysis
(Elsevier, 2024)
Failure analysis of welded joint with multiple defects was performed taking into account the effect of all defects, not just a dominant one. Four cases of multiple defects in welded joint under the uniaxial tensile loading ...
Residual life assessment of the historical road riveted bridges
(Elsevier, 2024)
Numerous roads and railways network steel bridges exist with more than 100 years in service, often of great historical value. The in-service safety assessment of these structures is a complex problem which requires ...
Microstructure and fracture of alloyed austempered ductile iron
(Elsevier Science Inc, New York, 2006)
An investigation has been conducted on two austempered ductile irons alloyed with Cu and Cu+Ni, austenitized at 900 degrees C and austempered at 350 degrees C. The microstructure and fracture mode developed through these ...
The strut – and – tie model for analysis of some RC foundation design
(Универзитет у Новом Саду Грађевински факултет СуботицаFACULTY OF CIVIL ENGINEERING Subotica, 2018)
Technical beam theory is not applicable for the analysis of non-standard
reinforced concrete structural elements (D-region), especially when members are
exposed to significant shear stress and/or torsion. In this case ...
STRESS CALCULATION AND DEFORMATION OF TANKS LOADED BY INTERNAL GAS PRESSURE LOCATED IN CITY HEATING PLANTS
(Structural Integrity and Life, 2022)
The paper presents the procedure for calculating stress
in gas pressure tanks using finite shell elements for linear
and geometrically nonlinear analysis. Therefore, a procedure has been developed to automatically generate ...

Assessment of Grain Size and Grain Refinement Efficiency by Calculation of Released Heat Attributed to Formation of Primary Aluminum Crystals During Solidification of Al7Si4Cu Alloy
(Springer India, New Delhi, )
Assessing heat released only related to the formation of primary crystals provides results with a significantly higher sensitivity than a traditional assessment of undercooling value. In this work, two similar Ti5B1 master ...
Life Assessment of Corroded Wire for Prestressing
(MDPI, 2023)
The repair of structural elements for the prestressing of reinforced concrete is necessarywhen existing prestressing wires are damaged or after a certain period of time. The objective of thispaper is to describe the ...
