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 ...
New modular concept for the helium cooled pebble bed test blanket module for ITER
(Elsevier Science Sa, Lausanne, 2005)
Starting from the latest European design of the HCPB blanket for the DEMO a test blanket module for ITER has been deduced. The paper describes the new design and presents the rational of the design choices and the results ...
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. ...
Plane strain fracture toughness of MP35N in aged and unaged conditions measured using modified CT specimens
(Elsevier Science Sa, Lausanne, 2003)
The multiphase alloy MP35N (35% Ni, 35% Co, 10% Mo, 20% Cr) is a high strength, high toughness alloy of choice for several safety-critical applications in aerospace, oil drilling, and biomedical industries. Several previous ...
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 ...
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. ...
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 ...
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 ...
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 ...
Compressive strains and displacement in a partially dentate lower jaw rehabilitated with two different treatment modalities
(Wiley, Hoboken, 2012)
Background: Understanding of the biomechanical consequences of the stresses generated to the supporting bone during occlusal loading is significant for improving the design and clinical planning process in partial edentulism ...
