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 ...
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. ...
Kinetics of the hydrogen evolution reaction on Fe-Mo film deposited on mild steel support in alkaline solution
(Pergamon-Elsevier Science Ltd, Oxford, 2005)
The mechanism and kinetics of the hydrogen evolution reaction were studied. in 1.0 mol dm(-3) NaOH solution on Fe-Mo alloy electrodes prepared by electrodeposition at constant current densities from a pyrophosphate bath. ...
The Influence of Low-temperature Plasma Treatment on Hemp Fabric Dyeability
(American Institute of Physics, Melville, 2004)
Low-temperature plasma treatment of hemp fabric causes an increase of dyeing rate, final dye exhaustion and Kubelka-Munk values of dyed samples. The positive effect of plasma treatment is more prominent in case of dyeing ...
Semi-interpenetrating polymer networks composed of poly(N-isopropyl acrylamide) and polyacrylamide hydrogels
(John Wiley and Sons Inc., 2004)
Three series of semi-interpenetrating polymer networks, baaed on crosslinked poly(N-isopropyl acrylamide) (PNIPA) and 1 wt % nonionic or ionic (cationic and anionic) linear polyacrylamide (PAAm), were synthesized to improve ...
The effect of segment length on some properties of thermoplastic poly(ester-siloxane)s
(John Wiley and Sons Ltd, 2003)
A series of novel thermoplastic elastomers, based on poly(dimethylsiloxane) (PDMS) as the soft segment and poly(butylene terephthalate) (PBT) as the hard segment, were synthesized by catalyzed two-step, melt transesterification ...
Immobilization of invertase on a new type of macroporous glycidyl methacrylate
(Kluwer Academic Publ, Dordrecht, 2001)
Invertase was immobilized via its carbohydrate moiety. The immobilized enzyme has a specific activity of 5500 IU g(-1), with 45% activity yield on immobilization. In a packed bed reactor, 90% 2.5 M sucrose was converted ...
INVESTIGATION OF DIELECTRIC PROPERTIES AND ELECTRIC RESISTANCE OF SOME TEXTILE MATERIALS
(Belgrade : Serbian Physical Society, 2003)
It is well known that textile materials are mostly dielectrics. Dielectric properties of textile materials condition the phenomenon of static electricity during their contact with other objects. This often has a negative ...
