Critical crack assessment procedure for high pressure steam turbine rotors
(Fatigue & Fracture of Engineering Materials & Structures, 1995)
Abstract A critical crack assessment procedure for high pressure steam turbine rotors is introduce and applied. The processes relating to low‐cycle thermal fatigue (LCTF), high‐cycle fatigue (HCF) and creep are considered ...
Group theoretical formulation of nonsymmetrical systems by the group supermatrix procedure
(Pergamon-Elsevier Science Ltd, Oxford, 1999)
The group supermatrix procedure, developed by Zlokovic for systems with symmetry properties described by groups, can be also applied to systems without symmetry. Transformation of a nonsymmetrical system into a system with ...
Temperature and moisture distributions inside the layer of moist material placed on hot isothermal surface
(Inzhenerno-Fizicheskii Zhurnal, 2001)
The problem of contact drying of a layer of moist material placed on a hot isothermal surface is considered. A system of heat and mass transfer equations and equations for the initial and boundary conditions are proposed. ...
Evaluation of residual life of steam turbine rotors
(Mezhdunarodnaya Kniga, Moscow, Russian Federation, 1995)
A consideration is given to the problem of determining remaining operational life of steam turbine rotors at the following mechanisms of crack initiation and propagation: low-cycle thermal fatigue, high-cycle fatigue and ...
The influence of microstructure on ductile fracture initiation in low-alloyed steel
(Trans Tech Publications Ltd, Durnten-Zurich, 2004)
In this paper the quantitative microstructural analysis of low-alloyed pressure vessel steel has been discussed. The values of volume fraction and mean free path of non-metallic inclusions determined in that way were used ...
Strength, toughness and structural integrity of storage tanks in urban environment
(Welding Research Council, 2003)
Urban development requires the application of different kind of storage tanks for liquid and gaseous fluids, which can also be hazardous and detrimental. In order to prevent the leakage and, eventually, catastrophic failure ...
Using Open Standards Based Building Information Modelling to Simulate Actual Design and Construction Processes
(Education and research in Computer Aided Architectural Design in Europe, 2011)
The paper describes pilot project conducted to achieve first understanding of the IFC standard and BIM process in Serbia. During the project a research team have developed information model of the actual building using IFC ...
Surface characterisation of Pb1-XMnXTe alloy by atomic force microscopy and magnetic force mode
(MANEY PUBLISHING, LEEDS, 2011)
In this paper the authors present the results of surface characterisation of a lead telluride alloy conducted by atomic force microscopy and magnetic force microscopy. Relationship between surface morphology, in the range ...
HETRA experiment for investigation of heat removal from the first wall of helium-cooled-pebble-bed test blanket module
(Elsevier Science Sa, Lausanne, 2011)
This paper presents an experimental test section which has been developed at the Institute for Neutron Physics and Reactor Technique in Karlsruhe Institute of Technology for investigations of heat removal from the first ...
Methodology of physical occurrences analogy in researching vehicle lifetime
(Technics Technologies Education Management, 2011)
Lifetime as a critical dimension of the quality of a product is most often studied using the unreliability curve, when there are problems in determining the origin in terms of time limit (Delta t), since monitoring usually ...
