Micromechanical analysis of constraint effect on fracture initiation in strength mismatched welded joints
(Trans Tech Publications Ltd, 2007)
In this paper the micromechanical approach to ductile fracture was applied in a study of constraint effect on crack growth initiation in mismatched welded joints. The single-edged notched bend specimens (precrack length a ...
Crack tip strain on ship and in situ measurement in shipyards
(IFAC Secretariat, 2007)
The paper presents the application extent of procedures for measurement deformations on ships. The actual deformation distribution was measured on the surface of the specimen by the optical grating method (OGM) parallel ...
Numerical and analytical modeling of elastic-plastic fracture mechanics parameters
(Trans Tech Publications Ltd, 2007)
Structural integrity and service reliability depend on the fracture resistance of a material. Cracks in the material are the locations of stress concentration, and elastic-plastic deformation can occur causing the development ...
Electron detachment of h- ions in hydrogen discharge
(Astronomical Observatory, Belgrade, 2008)
We present results of Monte Carlo simulation (MCS) for detachment rate coefficient for H- ions in H-2 and for modeling of spatiall dependence of apparent detachment excitation coefficient at very high E/N in a Townsend discharge.
Analytical model of a Si TFT with cylindrical source and drain
(IEEE, New York, 2008)
In this paper a new analytical model of a silicon Thin Film Transistor (Si TFT) with cylindrical source and drain, is presented. In first part of the text. some basic TFT characteristics and possible applications are ...
Experimental research of a collision energy absorber of a passenger train
(Institute of Mechanical Engineering, 2009)
Aging of solar cells under working conditions
(National Institute of Optoelectronics, 2007)
Rapid development and wide application of photovoltaic (PV) solar systems are primarily based on thorough investigations of the characteristics of solar cells. Though proved to be relatively stable (except perhaps amorphous ...
Predictions of heat transfer from a flat plate to impinging jet by numerical simulations
(Silesian University of Technology, 2008)
A numerical investigation is carried out to predict heat transfer and turbulent fluid flow in an axisymmetric turbulent impinging jet. Four common near-wall two-equation-and three Reynolds stress models were considered in ...
Development and application of crack parameters
(Springer, Dordrecht, 2009)
The development, definition and implementation of crack parameters (stress intensity factor, crack tip open displacement, J integral, filial stretch zone) are presented. They are now used for structural integrity and ...
Models of interactions of laser beams with materials of interest for optical components and provoked damages
(Polish Academy of Sciences, 2007)
Models of interactions of laser beams with materials of interest for optical components are presented in this paper. Special attention is paid to damages which appear within both active materials and optical components ...
