OTRC Project Summary

Project Title:	Finite Element Analysis of a Coiled Composite Tubular
Prinicipal Investigators:	Ozden Ochoa
Sponsor:	National Science Foundation
Completion Date:	March, 2000
Final Report ID#	A104(Click to view final report abstract)

The objective of this research is to provide a computational assessment of a spoilable, composite tubular, under the typical working loads of a drilling riser, and the bending loads due to storage using a commercial finite element package.  In order to facilitate coiling, the tube wall in this study has a complex sequence of a polyethylene liner, hoop-wound glad/epoxy sections within rubber, and an outer layer of unidirectional glass/epoxy reinforcement.
