Abstract
The elastic and yield response of extruded thinwalled high-density polyethylene tubes with a density in the range of 0.961 to 0.964 gm/cm3 was investigated. Material properties in the axial and hoop directions were measured, and the tubes were found to be mildly transversely isotropic. The yield response was pressure sensitive, and was well predicted using the pressure-modified Hill criterion using a compressive to tensile yield strength ratio of 1.12.
