Abstract

This investigation presents a theoretical and experimental analysis of the creep of thick-walled cylinders under the combined loading of internal pressure and axial load. The theory is based on the usual assumptions of infinitesimal deformations, incompressible material and that the total strain theory is valid. The stress-strain-time relation for the material is assumed to be represented by an isochronous stress-strain diagram which is approximated by an arc hyperbolic sine function. Experimental data were obtained for high density polyethylene thick-walled cylinders of outside to inside radii ratios of 1.5 and 2.0. The test cylinders either were tested as closed-ended cylinders under internal pressure only or were subjected to a combination of internal pressure and axial load. Also, the application of the theory for varying load conditions were studied. The theory and experiment were in good agreement.
