Structured-wall high density polyethylene pipes up to 3m diameter are used extensively in civil engineering applications including storm water attenuation tanks, culverts, surface drainage, inter-process pipe work, sewers. A key quality control measure for the manufacture of such pipes is the ringstiffness to BS EN 1446: 1996. The ability to predict this accurately and inexpensively as a function of the pipe wall geometry is a pre-requisite for optimization of the pipe design. The paper describes the development of Finite Element modeling of the ringstiffness test as well as an optimization procedure containing opensource and in-house software only. The material saving capabilities will be discussed by means of two optimization examples.
