Research ArticleOpen accessIn the keywordsModification Approach of Fuzzy Logic Model for Predicting of Cutting Force When Machining Nickel Based Hastelloy C-276Basim A. Khidhir, Bashir Mohamed, Mahmoud A.A. YounisProblem statement: Most Nickel based Hastelloy C-276 is a difficult-to-machine material because of its low thermal diffusive property and high strength at high temperature. Machinability consideration of nickel based Hastelloy C-276 in turning operations has been carried out using ceramic inserts under dry conditions. Approach: This study described a modification approach applied to a fuzzy logic based model for predicting … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 1 · 31 Mar 2010 · 8,456 accessesView PDF Cite

Research ArticleOpen accessIn the abstractReliability Assessment of Buckling Strength for Compressed Cylindrical Shells with Interacting Localized Geometric ImperfectionsJalal El Bahaoui, Abdellatif Khamlichi, Larbi El Bakkali, Ali LimamProblem statement: Elastic cylindrical shells are common structures in the fields of civil engineering and engineering mechanics. These thin-walled constructions may undergo buckling when subjected to axial compression. Buckling limits to large extent their strength performance. This phenomenon depends hugely on the initial distributed or localized geometric imperfections that are present on the shell structure. Localized geometric imperfections result in … …American Journal of Engineering and Applied Sciences, Vol. 3, Issue 4 · 4 Nov 2010 · 8,320 accessesView PDF Cite
