Sažetak

In this paper we present a model for the experimental and numerical study of helical shells. Three different forms were chosen for the experiment: Model A forms a helicoidal shell on a cylindrical shell, Model B is an annular shell on a cylindrical shell and Model C a rectangular plate on a cylindrical shell.. Placing a continuous load on the surface of the shell was achieved by normal pressure, thanks to special sealing elements within the construction of the double helical shell.The strain was measured using strain gauges. Comparable results were obtained using the ANSYS Workbench software package for analysis using the finite element method. The experimental investigation confirmed that the numerical modelling provides relevant results for the stress, deformation and deflections of continuously loaded helical shells.
