【摘要】 提出了一种新的基于图像灰度梯度迭代的数字散斑相关方法(DSCM,digital speckle correlation method)。通过使用DSCM测量碳纤维复合材料压力容器在水压下的局部区域的位移场和应变场,分析了复合材料压力容器的轴向和环向的变形特征,为碳纤维复合材料压力容器的优化设计提供了理论和实验依据。更多还原

【Abstract】 A new digital speckle correlation method(DSCM) based on iterative and spatial-gradient algorithm was presented.It was used to measure the deformation of carbon fiber composite pressure vessel under water pressure.The deformed characterizations along axis and ring direction are analyzed.The experimental results may be used for optimum design of carbon fiber composite pressure vessel.更多还原
