The effect of layup on localised strains in GRP pipes and storage vessels
- Univ. of Strathclyde, Glasgow (United Kingdom). Dept of Mechanical Engineering
The increasing use of glass reinforced plastic pipes and storage vessels in chemical and process plant has stimulated the need to provide accurate assessment of their behavior under a variety of load applications. The possibility of laminating these components in different ways, taking account of the material anisotropy, gives a design flexibility which is unique to the laminated system over its metallic counterpart. In this paper an analytical approach is outlined for laminated pipes and vessels. This permits the consideration of a variety of alternative layups, which are both symmetric and non-symmetric through the wall. A number of alternative layups have been considered and methods for obtaining optimum designs investigated. Particular attention is directed to the support regions, where high strain values can cause cracking of the matrix on the inside surface of the vessel. Such local cracking would allow hostile liquid ingress to the glass and could cause premature local failure of an otherwise high integrity component.
