Abstract

Despite the development of many important concepts to predict material behavior and failure, the prediction of failure modes and strength of composite materials is still a challenge within the framework of the finite element method (FEM). Recently, the Air Force Research Laboratory (AFRL) conducted Tech Scout Project in order to evaluate the existing progressive damage prediction methods. As part of this project, the AFRL tested open-hole laminates for three different layups under tension and compression for strength and failure progression. Using the ply level properties of the IM7/977-3 composite provided by the AFRL, the participants in this project reported their predictions and comparison with test results in a series of papers during AIAA SciTech 2014. With the data made available by the AFRL, this study presents the stiffness, strength and damage progression predictions in each ply by using peridynamics. Comparison between numerical prediction and experimental data show good agreement.
