Modelling of ductile fracture initiation in strength mismatched welded joint
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
In this paper, the effect of strength mismatch and width of the welded joints oil the stress-strain distribution in the crack tip region has been discussed. The single-edge notched bend (SENB) specimens (precrack length ...
The austempering study of alloyed ductile iron
(Elsevier Sci Ltd, Oxford, 2006)
Austempered ductile iron (ADI) proved to be an excellent material as it possesses attractive properties: high strength, ductility and toughness are combined with good wear resistance and machinability. These properties can ...
A computer code for the prediction of mill gases and hot air distribution between burners' sections at the utility boiler
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
One of the main tasks during the design or simulation and analyses of the utility steam boiler operation is the prediction of a distribution of mill gases and hot air flow rates between burners' sections. These are the ...
Ductile crack growth initiation in welded joints - Micromechanical approach
(Welding in the World, 2008)
The integrity of welded structures depends on the load-carrying capacities of their welded joints. Having in mind that welding process produces a large microstructural gradient through the weld, resulting in variation of ...
Defining the memory function for tension and deformation of linear textile products on the basis of their rheological models
(Industria Textila, 2009)
Defining the memory function for tension and deformation of linear textile products on the basis of their rheological models On the basis of rheological models for yarn elongation, which have been set out for three different ...
Design update and mock-up test strategy for the validation of the eu-hcpb-tbm concept
(Taylor & Francis Inc, Philadelphia, 2009)
In the frame of the activities of the EU Breeder Blanket Programme and of the Test Blanket Working Group of ITER, the Helium Cooled Pebble Bed Test Blanket Module (HCPB-TBM) is developed to investigate DEMO relevant concepts ...
Failure analysis of the end eye connection of the bucket wheel excavator portal tie-rod support
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
This paper describes the failure analysis results of the bucket wheel excavator (BWE) portal tie-rod support. The results of finite elements analysis (FEA) point out the occurrence of pronounced stress concentration, whereby ...
Analysis of the unstable fracture behaviour of a high strength low alloy steel weldment
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
Local brittle zones (LBZ) cause the unstable fracture behaviour of weld metals. This threatens the safe service of welded structures and makes structural assessment procedures difficult. Therefore, the unstable fracture ...
Determination of ductile crack initiation by magnetic emission and potential drop techniques using pre-cracked Charpy specimens
(European Structural Integrity Society, 2002)
Magnetic emission (ME) and potential drop (PD) techniques were used for instrumented Charpy impact testing in order to determine critical crack initiation properties of standard pre-cracked three-point bending specimens ...
Formation of fouling layers on a heat exchanger element exposed to warm, humid and solid loaded air streams
(Elsevier Science Inc, New York, 2002)
In consideration of the very high energy consumption of drying processes it is astonishing and disadvantageous that the majority of industrial dryers are offered and operated without energy recovery. The avoidance of fouling ...
