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 ...
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. ...
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. ...
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 ...
Thermal-hydraulic analysis of a steam boiler with rifled evaporating tubes
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Rifled evaporating tubes are applied in the steam boilers with the aim to increase the steam-water mixture turbulization and to prevent the burnout of tubes walls. The rifled evaporating tubes and the working fluid forced ...
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 ...
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 ...
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 ...
Mock-up testing facilities and qualification strategy for EU ITER TBMs
(Elsevier Science Sa, Lausanne, 2010)
European test blanket modules (TBM) for both European blanket concepts, namely the Helium Cooled Lithium Lead (HCLL) and the Helium Cooled Pebble Bed (HCPB), and their auxiliary systems have been designed in the last years. ...
