Abstract

This study presents an ordinary state-based peridynamic model (OSB PD) for open-hole tensile strength prediction of fiber-reinforced composite laminates. The transverse Poisson’s effect of composites is considered in the present OSB PD composite model, ensuring a precise capture of typical damage patterns and failure modes of composite laminates, especially when capturing the effect of thickness on damage patterns. The out-of-plane bond considers not only the adjacent plies, but also all the plies within the spherical horizon. The in-plane mesh could be much larger than the out-of-plane mesh, forming an “uneven spherical horizon”. The validation of the present model is demonstrated by several numerical results. Typical damage patterns and failures modes of open-hole composite laminates under tensile loading are illustrated, and the effect of thickness on damage patterns is also discussed.
