dc.description.abstractThe failure mechanism of composite bolted joints was investigated using an in-situ X-ray CT technique with SSB test. A physics-informed modeling approach was proposed based on the traditional CDM method and a static bearing model. Residual stress in the longitudinal and transverse direction is considered due to the out-of-plane constraint in the bearing region. Meanwhile, a micromechanics model was adopted to predict the fiber kinking behavior of composite laminates under different constraints. The effects of the constraint on the compressive strength and kinking band angle were studied. The modeling approach was validated using SSB tests by comparing the stress-strain response and corresponding failure patterns.en_US
