Research ArticleOpen accessIn the keywordsEstimation of C*-Integral for Radial Cracks in Annular Discs under Constant Angular Velocity and Internal PressureA.R. Gowhari-Anaraki, F. Djavanroodi, S. ShadlouThe finite element method has been used to predict the creep rupture parameter, C*-Integral for single and double-edge cracks in eight annular rotating discs under constant angular velocity with and without internal pressure. In this study, a new dimensionless creeping crack configuration factor, Q* has been introduced. Power law creeping finite element analyses have been performed and the results are … …American Journal of Applied Sciences, Vol. 5, Issue 8 · 31 Aug 2008 · 6,721 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsEstimation of C*-Integral in Thin T-Sections Subjected to Projection and Remote Loading Base on Elastic Stress Concentration FactorA.R. Gowhari-Anaraki, F. Djavanroodi, S. ShadlouThe finite element method has been used to predict the creep rupture parameter, C*-Integral of flat T-section bar subjected to loaded projection and remote loading with a crack or crack-like flaw introduced in the fillet (i.e., high stress) region of the component. In this study, a new dimensionless creeping crack configuration factor, Q* has been introduced. Power low creeping finite … …American Journal of Applied Sciences, Vol. 5, Issue 5 · 31 May 2008 · 6,469 accessesView PDF Cite

Research ArticleOpen accessIn the abstractEffect of Different Cycles of Thermal Fatigue in Steel Metallurgical Aspects ASTM SA-516 Grade 60Eder Hermes Bicharra, Jorge Luis Braz Medeiros, Luciano Volcanoglo Biehl et al.The ASTM SA-516 steel has applications in compact steam boilers of low and medium temperature and pressure. Deterioration can show when exposed to high temperatures due to fuel gases burning. Failures detected by inspections done in a frequency required by standard on the boilers. Among the main failure mechanisms found in materials used in boilers, creep, corrosion, when subjected to … …American Journal of Engineering and Applied Sciences, Vol. 13, Issue 3 · 28 Aug 2020 · 6,985 accessesView PDF Cite
