Wrinkle defects were found widely exist in the field of industrial products, i.e. wind turbine blades and filament-wound composite pressure vessels. The magnitude of wrinkle wavelength varies from several millimeters to over one hundred millimeters. Locating the wrinkle defects and measuring their responses are very important to the assessment of the structures that containing wrinkle defects. A meso-mechanical modeling is presented based on the homogenization method to obtain the effective stiffness of a graded wrinkle. The finite element simulation predicts the trans-scale response of out-of-plane displacement of wrinkled laminates, where the maximum displacement ranges from nanoscale to millimeter scale. Such trans-scale effect requires different measurement approaches to observe the displacement responses. Here we employed Shearography (Speckle Pattern Shearing Interferometry) and fringe projection profilometry (FPP) method respectively according to the different magnitude of displacement. In FPP method, a displacement extraction algorithm was presented to obtain the out-of-plane displacement. The measurement sensitivity and accuracy of Shearography and FPP are compared, which provides a quantitative reference for industrial non-destructive test.

皱纹缺陷广泛存在于工业产品领域中，例如风力涡轮叶片和缠绕复合材料压力容器。基于均质化方法提出了一种介观力学建模，以获取分级皱纹的有效刚度。有限元模拟预测了皱纹层合板的跨尺度反应，其中最大位移范围从纳米到毫米级。根据位移的不同量级，使用剪切法光（Speckle Pattern Shearing Interferometry，简称Shearography）和条纹投影轮廓法（Fringe Projection Profilometry，简称FPP）方法进行测量，比较了剪切法光和FPP的测量灵敏度和准确性，为工业无损测试提供了定量参考。
