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 ...
Analysis of welded tensile plates with a surface notch in the weld metal and heat affected zone
(Pergamon-Elsevier Science Ltd, Oxford, 2010)
The behavior of the plates with a surface notch under tensile external loading is experimentally and numerically analyzed. The specimens were made of micro-alloyed steel NIO-MOL 490 K. welded by MAC (CO2) welding method. ...
Load-bearing steel structure diagnostics on bucket wheel excavator, for the purpose of failure prevention
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
The appearance of cracks on load-bearing steel structure of compact, hydraulic bucket wheel excavator was a perennial problem. Unfavourable stress concentration, inadequate geometry and structure of materials, inadequate ...
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 ...
Balance of liquid-phase turbulence kinetic energy equation for bubble-train flow
(Atomic Energy Soc Japan, Tokyo, 2004)
In this paper the investigation of bubble-induced turbulence using direct numerical simulation (DNS) of bubbly two-phase flow is reported. DNS computations are performed for a bubble-driven liquid motion induced by a regular ...
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 ...
Prediction of ductile fracture initiation using micromechanical analysis
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
In the paper ductile fracture initiation analysis of low-alloyed ferritic steel has been made by application of two micromechanical models: the Rice-Tracey void growth model and the Gurson-Tvergaard-Needleman (GTN) model. ...
Group theoretical formulation of quadrilateral and hexahedral isoparametric finite elements
(Pergamon-Elsevier Science Ltd, Oxford, 2004)
The group supermatrix procedure, developed by Zlokovic, is applied for derivation of stiffness matrices of quadrilateral and hexahedral isoparametric finite elements using the symmetry groups C-2v and D-2h respectively. ...
Model analysis of bucket wheel excavator SchRs 630 strength
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The possibilities of testing real constructions are often limited, especially in case of large constructions. The idea of model testing is to create a sub-scaled model in order to anticipate the behavior of the real ...
Fracture properties of multiphase alloy MP35N
(Elsevier Science Sa, Lausanne, 2003)
This paper addresses the fracture properties of commercially cold-drawn (53%) MP35N (35% Co, 35% Ni, 20% Cr, and 10% Mo) in both the cold-worked and the cold-worked and aged conditions. MP35N is a superalloy that exhibits ...
