Dynamic Recovery Characterization of Anisotropic Composites Under Axial and Internal Loading for Deformation and Damage Mechanisms
Abstract
This research seeks to extend the traditional split Hopkinson bar approach for characterizing anisotropic composite materials through the reproduction of the internal pressure loading, measurement of response and evaluation of the failure modes. The experimental results derived under this program will enable expansion of constitutive models of heterogeneous anisotropic media via direct calibration, identifying gaps in models, and novel dynamic homogenization approaches. Furthermore, such models could be integrated through custom UMAT subroutines in large scale FE codes (commercial or military) to predict impact and blast behavior of more complex systems.
