Micromechanical coupled study of crack growth initiation criterion in pressure vessel steel
(Strength of Materials, 2004)
We present results of the combined design-theoretical investigation of the mechanism of crack growth at the onset of ductile fracture of NPP reactor pressure vessels. Micromechanical approach to the prediction of ductile ...
Optimization of elevator regimes of movement
(China Machine Press, Beijing, 2004)
The paper presents the procedure for determining the optimal regimes of movement of the elevator cabin as a function of input values such as: distance that elevator cabin has to pass, acceleration, velocity and jerk of the ...
Effects of structure characteristics on mechanical properties of aluminum alloy matrix composites
(Trans Tech Publications Ltd, 2004)
Composite materials based on the CW67 alloy (Al base matrix) and volume fraction of 15 pet of SiC particles in two nominal sizes (0.7 μm and 33 μm) have been produced by hot pressing. The fracture behavior of the composite ...
Some aspects of engineering approach to structural integrity assessment

An introductory study of helicopter main rotor blade aerodynamic shape optimization problem is presented. Optimization process is carried out in compressible, viscous, quasi-steady fluid flow field of hovering rotor described ...
Design of the breeder zone for the eu helium cooled pebble bed test blanket module for iter
(Proceedings - Symposium on Fusion Engineering, 2009)
This paper summarizes the design and development activities for the EU Helium Cooled Pebble Bed Test Blanket Module (HCPB TBM) Breeder Zone (BZ) performed in 2007 and 2008. The BZ design, based on two parallel cooling ...
An analysis of the influence of weldment heterogeneity in ferrite-austenite welded structure
(Welding in the World, 2009)
An analysis of the influence of heterogeneity of the ferriteaustenite welded joint on its integrity has been performed. The Charpy specimens, with notch positioned in different regions of welded joint, have been tested ...
