With fluid forming processes getting more and more common in industrial application a lot of research is carried out to analyze the forming behavior of sheet metal within these processes. In order to gather experimental information about the forming behavior of the workpiece, an imaging system is presented, that will allow determining the actual shape within the forming process. The system has ...

A method is presented to predict the complete stress-strain curves of concrete subjected to triaxial stresses, which were caused by axial load and lateral force. The stress can be induced due to the confinement action inside a special-shaped steel tube having multiple cavities. The existing reinforced confined concrete formulas have been improved to determine the confinement action. The influen...

This study explores the application of zigzag-shaped, finless tubes in enhancing heat transfer performance within exchangers. Using three-dimensional numerical simulations, we examined per unit area and volume pressure drop, comparing these findings with a traditional parallel tube exchanger. innovative design strategy involved arranging zigzag-shaped at varying distances, thermal frictional ch...
