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 ...
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 ...
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 ...
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 ...
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 ...
Case study of supporting tubes failure

Fracture toughness of alloyed austempered ductile iron (ADI)
(Kluwer Academic Publishers, 2006)
Work analysis of the energy steam boiler evaporator with sliding pressure of 350 MW block
(Nis University, 2011)
Within Electric Power Utility of Serbia 1991. a thermal power plant "Kostolac B", power 2x350 MW started. Based on the examination of steam boiler pipe system, it is confirmed that it is in "bad" shape. It's most jeopardized ...
Sensitivity Equation for Transient Three-Dimensional Heat Conduction Problem with Moving Heat Source
(Amer Inst Physics, Melville, 2010)
Sensitivity analysis of transient three-dimensional heat conduction in a plate during process of welding is performed. Crank-Nicolson method with multi-step Douglas-Gunn Alternating Direction Implicit (AD!) method is used ...
The Influence of Power and Velocity of the Heat Source on Temperature Distribution in Plate Welding Problems
(Amer Inst Physics, Melville, 2011)
The main objective of this study is to compare results obtained from some widely used simplified analytical formulas of plate welding problem to results obtained from numerical analysis of this problem based on the solution ...
