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 ...
Experimental analysis of fatigue fracture behaviour of Ti-6Al-4V alloys
(Scientific Society for Mechanical Engineering, 2011)
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 ...
3-D model of solid and gas phase flow in the duct bend behind the mill gas classifier at the fan mill
(Nis University, 2011)
This paper shows the computer simulation of two-phase flow of the mill gases, the solid particles of monodisperse coal dust and the transport fluid. Numeric simulation was performed with the software pack Fluent 6.3.26, ...
Modelling of ductile crack growth in welded joints using micromechanical failure criterion
(17th European Conference on Fracture 2008: Multilevel Approach to Fracture of Materials, Components, 2008)
In this paper, ductile crack growth in strength mismatched welded joints is considered. High-strength low-alloyed (HSLA) steel in quenched and tempered condition is used as the base metal. Two different fillers are selected ...
Analysis of loading steel structure of bucket wheel excavator by stress condition measuring
(Institute of Mechanical Engineering, 2009)
A framework for comparative analysis of belgrade housing stock - determinants of carbon reduction strategy
(IBPSA 2009 - International Building Performance Simulation Association 2009, 2009)
Approximately 33% of total annual energy consumption and carbon emission in Belgrade (Serbia) are related to the housing sector. As such, the housing sector represents a key determinant in the development of an overall ...
Exponential tracking control of servomotor used for ships
(IFAC Secretariat, 2007)
Background: According to the fundamental importance of the tracking theory on technical systems (ship servomotor), the main goal of this paper is a further development of the theory and the application of the tracking, ...
