In the present work, the mechanical behavior of stress corrosion cracking phenomenon is described. Such phenomenon presents strong complexity due to metallurgic and electrochemical aspects. A methodology for modeling both SSR (Slow Strain Rate) and CL (Constant Load) tests based upon thermodynamics of continuum solids and elastoplastic damage is proposed. In this macroscopic approach, besides t...

The influence of the metal content (0-28 at.%) on the structural, mechanical and tribological properties of a-C:Cu films grown by pulsed filtered cathodic arc deposition is investigated. Silicon and AISI 301 stainless steel have been used as substrate materials. The microstructure, composition and bonding structure have been determined by scanning electron microscopy; combined Rutherford backsc...

The initial material cost of structural stainless steel is about four times that of structural carbon steel, due largely to the expense of the alloying elements and the relatively low volume of production. Given broadly similar structural performance, additional areas of benefit need to be identified and exploited in order to establish stainless steel as a viable alternative material for constr...

The objective of this paper is to describe and analyze a series of nonlinear finite element analyses used to compare three design methods for locally slender, braced, steel beams and columns. The three design methods are: (i) the hot-rolled steel AISC Specification, (ii) the coldformed steel AISI Specification which uses the effective width method throughout, and (iii) the cold-formed steel Dir...

In the work influence of thermal limiters on formation a dendritic structure stainless steel AISI 304L layer deposited by electric arc welding in argon medium was investigated. The billets investigated mode differential interference contrast. analysis obtained structures showed that use form graphite skids allows to obtain uniform without sharp transitions between layers.
