摘要：

Applications of the digital speckle correlation method (DSCM) for the full-field deformation measurement of carbon fiber/epoxy composite pressure vessel were investigated and the basic principles of displacement measurement by DSCM are briefly given. The full-field displacement and strain distribution of a composite pressure. vessel were evaluated under internal pressure. The results of the average strain value show a good agreement with the results from conventional electronic strain gauge technology. The results reveal that the DSCM is suitable for deformation measurement of composite pressure vessels in real engineering practice. (C) 2004 Elsevier Ltd. All rights reserved.
