Effects of structure characteristics on mechanical properties of aluminum alloy matrix composites
(Trans Tech Publications Ltd, 2004)
Composite materials based on the CW67 alloy (Al base matrix) and volume fraction of 15 pet of SiC particles in two nominal sizes (0.7 μm and 33 μm) have been produced by hot pressing. The fracture behavior of the composite ...
Micromechanical coupled study of crack growth initiation criterion in pressure vessel steel
(Strength of Materials, 2004)
We present results of the combined design-theoretical investigation of the mechanism of crack growth at the onset of ductile fracture of NPP reactor pressure vessels. Micromechanical approach to the prediction of ductile ...
Optimization of elevator regimes of movement
(China Machine Press, Beijing, 2004)
The paper presents the procedure for determining the optimal regimes of movement of the elevator cabin as a function of input values such as: distance that elevator cabin has to pass, acceleration, velocity and jerk of the ...
Weldability testing of microalloyed steel and integrity assessment of welded joint
(Institut International de la Soudure, 2005)
The results of weldability assessment of high strength low carbon microalloyed steel are presented. These results are used for integrity assessment of weldments. Two aspects of behaviour were considered. These are the risk ...
Static and dynamic fracture mechanics parameters of material in the heat-affected-zone
(11th International Conference on Fracture 2005, ICF11, 2005)
The behaviour of heat-affected-zone (HAZ) in welded joints of structural steels with different chemical composition and different strength class (yield strength ranged from 450 to 700 MPa) has been evaluated, applying two ...
Finite element evaluation of fracture mechanics parameters using rapid mesh refinement.
(Pergamon Press, Oxford, Engl, 1984)
Using machine learning techniques to enhance expressiveness of computer-based design systems
(Education and research in Computer Aided Architectural Design in Europe, 2000)
In face of the huge expansion of computer-mediated interaction among people, current representation-centered CAAD systems do not offer full information spectrum necessary to express all design intentions. Representational ...
From Number Cruncher to Digital Being: The changing role of computer in CAAD
(Education and research in Computer Aided Architectural Design in Europe, 1999)
The paper reflects on a thirteen-year period of CAAD research and development by a small group of researchers and practitioners. Starting with simple algorithmic drafting programmes, the work transcended to expert systems ...
Finite element modeling of pressure vessel with two internal surface crack
(11th International Conference on Fracture 2005, ICF11, 2005)
This paper deals with the finite element modeling of the pressure vessel with two artificial internal surface cracks, one positioned in the vessel center and the other one close to the vessel cover. Cracks are made by ...
Numeričko modelovanje otvaranja vrha prsline u zavarenom spoju / Numerical modeling of crack tip opening in welded joint
(Institut za ispitivanje materijala, Beograd, 2010)
Zavareni spoj je heterogene strukture sa područjima različitih mikrostruktura. Da bi ispitali lokalno ponašanje područja prateći otvaranje prsline, problem je postaviti vrh zareza u željeni položaj. Izvedena je simulacija ...
