Crack tip fields effects on crack propagation through the heat affected zone in an overmatched welded joint
(2023)
The mismatching constraint effect on crack propagation through the heat-affected zone (HAZ) in a welded joint is presented in this paper. It is shown that due to this effect, the fracture behavior of an overmatched welded ...
Application of open source solutions in the realization of low-cost teaching laboratories
(MIET2023-Odesa-Ukraine, 2023)
Teaching in engineering study programs includes practice that often takes place in laboratories. The implementation of these laboratories is often accompanied by certain limitations and complexities. This paper will show ...
LIFE CYCLE ASSESSMENT OF MAIN BIOMASS SUPPLY CHAINS IN SERBIA - INITIAL EVALUATIONS
(Full Papers Proceeding of International Conference "Power Plants 2023", November 2023, Zlatibor Serbia, 2023)
In this paper, life cycle assessment (LCA) of two biomass supply chains models in the Republic of Serbia were carried out: LCA of the wood and LCA of the agricultural biomass. These models were developed by analyzing data ...
Local approach to analysis of ductile fracture in welded joints-Influence factors
(18th European Conference on Fracture: Fracture of Materials and Structures from Micro to Macro Scale, 2010)
Local approach is applied to analysis of ductile fracture in steel welded joints. Welded single-edge notched bend (SENBspecimens with joints containing one or two weld metals are investigated. The Gurson plastic flow ...
An Approach to the Optimization of a Thin-walled Z-beam
(Strojniski Vestnik/Journal of Mechanical Engineering, 2009)
One approach to the optimization of a thin-walled open section Z-beam subjected to bending and to the constrained torsion is considered. For given loads, material and geometrical characteristics the problem is reduced to ...
Analysis of the Influence of Microstructure Heterogeneity and Mechanical Properties of Welded Joint Constituents on Fracture Toughness for Plane Strain, K-Ic
(Trans Tech Publications Ltd, Durnten-Zurich, 2012)
The problem of fracture toughness, K-Ic, determination at a crack tip localized in a welded joint is placed in principle because fracture mechanics assumes homogenous material, not only around the crack tip but on a distance ...
Influence of secondary phases in A356 MMCs on their mechanical properties at macro- and nanoscale
(Springer Heidelberg, Heidelberg, 2020)
Metal matrix composites are very inhomogeneous materials, and their properties depend on various parameters (production process, constituents, their interfaces, etc.). The influence of SiC microparticles (40 mu m) reinforcement ...
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 ...
The Influence of Modifying Methods on the Quality of Eutectic and Hypereutectic Silumine for Diesel Engine Pistons
(International Journal of Cast Metals Research, 2013)
The results of the investigation of the influence of different modifiers (sodium, phosphorus, antimony and strontium) on the quality of AlSi12CuMgNi and AlSi18CuMgNi alloys, which are used for the production of pistons, ...
