Formulation and implementation of peridynamic strength parameters and strain rate-dependent behavior of fiber-reinforced composite laminates are presented. This work builds on the earlier framework [1] objectively determining elastic parameters for laminates exhibiting shear nonlinearity. The formulation of the strength parameters uses energy-based failure criteria, specifically addressing intralaminar and interlaminar behaviors. A novel implementation of strain rate effects includes conversion from local strain to nonlocal stretch rates. The current peridynamic approach with shear nonlinearity and strain rate dependence accurately captures multiple experimentally measured metrics, including force vs. time, force vs. displacement, energy vs. time, and damage and delamination extents.
