Abstract

This paper presents an expansion loading technique for metal cylindrical shell to effectively achieve a one-dimensional, high-strength and quasi-static tensile loading on shell sidewall. A quasi-static axial compression is firstly loaded on the filling polymer via rock triaxial testing system (RTTS), which results in the internal pressure of filling polymer reaching up to the scale of 100MPa or even GPa. Such intensive pressure would give rise to a fierce radial expanding of the filling polymer and then consequently generate a uniform quasi-static radial loading on the inner surface of the shell, which provides a one-dimensional high-intensity tensile strength radially. Accordingly, the axial pressure-displacement curve could be recorded by RTTS to characterize the mechanical structural strength of cylindrical shells. This simple and efficient loading technique has been successfully applied to the measurement of the structural strength for Duralumin LY-12.
