摘要:
为弥补传统测试方法的不足,在外粘碳纤维增强复合材料(CFRP)混凝土试件的双剪试验中,首次引入双光束电子散斑干涉技术(ESPI),对粘贴面变形性能进行了测试.通过防止刚体位移、调暗背景光、保持物面平整,得到理想的条纹图,测出了粘贴面上的波长量级的全场位移量.
Abstract:
In order to overcome the drawbacks of traditional measurement methods, electronic speckle pattern interferometry(ESPI)technique is used to study the character of bond area in the FRP-concrete double-face shear test. Some factors affecting the quality of fringe patterns are taken into account and clean fringe patterns are obtained by using dark background light, preventing movement of rigid body, and keeping the test surface even. Accurate full-field in-plane displacements are measured.
