采用三维数字散斑相关方法研究了碳纤维/环氧复合材料压力容器的三维全场变形。简要介绍了三维数字散斑相关方法的基本原理。计算了复合材料压力容器在内压载荷作用下的三维全场位移和应变分布。平均应变值显示出良好的协议，从传统的电阻应变计技术获得的结果。结果表明，三维数字散斑相关方法适用于真实的工程实践中复合材料压力容器的变形测量。
The 3D full-field deformation of a carbon fiber/epoxy composite pressure vessel are studied using a 3D digital speckle correlation method. The basic principles of 3D digital speckle correlation method are briefly introduced. The 3D full field displacement and strain distribution of the composite pressure vessel were evaluated under internal pressure loading. The average strain value shows good agreement with the results obtained from conventional electrical-resistance strain gauge technology. The results reveal that the 3D digital speckle correlation method is suitable for deformation measurement of composite pressure vessels in real engineering practice.
