Abstract Pipe bends are generally employed for routing piping systems by connecting to straight pipes but back-to-back pipe bends are often necessary for confined space applications. In order to achieve safe operation under complex loading, it requires a thorough pipeline integrity assessment to be commenced. This paper investigates the effects of cyclic thermo-mechanical loading on cyclic plastic behavior of a 90-deg back-to-back pipe bend system, including temperature-dependent yield stress effects. Structural response interaction boundaries are determined for various different combinations of cyclic and steady loading. Constructed structural responses are verified by full cyclic incremental, step-by-step, finite element analysis. The numerical studies provide a comprehensive description of the cyclic plastic behavior of the pipe bends, and semi-empirical equations for predicting the elastic shakedown limit boundary are developed to aid pipeline designers in the effective assessment of the integrity of the pipe bends without a requirement for complex finite element analysis.

Aim: This study compared the stress distributions of endodontically treated tooth restored with carbon and titanium post under thermal and mechanical loading conditions. Methodology: A 3-dimensional finite element model was created to represent in a labiolingual cross-sectional view of an endodontically treated maxillary central incisor tooth with its supporting structures. It was modified according to two post systems with different physical properties consisting titanium, and carbon fiber. Stress distribution and stress values were then calculated by considering the three dimensional von Mises stress criteria. Results: A 100-N static vertical occlusal load was applied on the node at the center of occlusal surface of the tooth. The von Mises stress values for carbon post model was on the coronal third and the cervical area of the root in the range of 436,16 and 3,59 MPa,  for titanium post model was 590,55 and 3,05 MPa. Thermal stress values for carbon post model showed that maximum stress concentrations were noted on the coronal third and the top of the post area of the root in the range of 509,94 and 6,38 MPa. Titanium post model showed that maximum stress concentrations were noted on the coronal third and top of the post area of the root in the range of 1165,06 and 3,06 MPa. Conclusion: This study shows that the titanium post yields larger stresses than the carbon post under thermal conditions.  How to cite this article: Adıgüzel Ö, Yiğit Özer S, Bahşi E, Yavuz İ.
