Project Number 365
Date of Summary September 24, 2004
Subject Composite Coiled Tubulars: Effects of Viscoelasticity
Performing Activity Texas A&M University, Offshore Technology Research Center (OTRC)
Principal Investigator Ochoa, Whitcomb, and Schapery
Contracting Agency Minerals Management Service
Estimated Completion September 2002
Description Experimental and theoretical work developed explicit models for predicting effects of Viscoelasticity and time-dependent damage on deformation and damage response of composite coiled tubulars. The experimental work used viscoelastic property tests (creep, recovery and constant rate) on composite tubes and uniaxial specimens cut from tubes.
