Abstract: The fiber cross undulation pattern and the holes on the members will affect the mechanical behavior of the composite structure. In order to study the tensile mechanical behavior and failure mechanism of the open-hole composite laminates and open-hole filament wound panels, the digital image correlation (DIC) technology was adopted by this paper to carry out quasistatic tensile tests on the specimens. The macro-mechanical behavior of the two different structures was determined, and the influence characteristics of the structures on the full-field strain distribution and the final damage pattern were investigated. The influence of the structure on the full-field strain distribution and the final damage morphology was investigated. Two kinds of finite element models were established: the mesoscale model of open-hole filament wound structure and the macroscopic equivalent model of open-hole laminated structure, and the numerical simulation of tensile members was realized by introducing the shear nonlinear equations and the strain-based 3D Hashin. The results show that the standard open-hole laminates have better tensile load carrying capacity, being affected by the fiber cross undulation pattern and the open holes, the open-hole wrapped have strain concentration phenomena in the open-hole and cross-undulation regions, which also have an impact on the damage. The mesoscale finite element model accurately simulates the strain evolution and final damage under the coupling of yarn gap, fiber cross undulation pattern and open holes, and the numerical analysis results are in good agreement with the experimental results.
