As an example of use, Smith and Haigh diagrams were obtained for titanium alloy (Ti-6Al-4V) components, which enable to estimate the fatigue strength for the designed fatigue life, known load ratio and certain number of HCF cycles per one combined stress block.</dc:description><dc:date>2003</dc:date><dc:date>2012-06-01 12:07:50</dc:date><dc:type>Neznano</dc:type><dc:identifier>27721</dc:identifier><dc:language>sl</dc:language></rdf:Description></rdf:RDF>
