Abstract: This research aims to enhance the knowledge on stress-strain states of a copper pipe coil facility used for hydraulic transient experiments. The ultimate goal is the development of the pipe movement equations which will allow the implementation of Fluid-Structure Interaction (FSI) in the hydraulic transient model. The membrane theory of shells of revolution has been applied for the description of axial and circumferential strains while an inverse method has been used to analyze bending effects. Finally, the developed stress-strain model has been successfully validated for dynamic loading.
