Abstract:
This study examines the hydrodynamic response of composite laminate plates reinforced with Kevlar 29 and Dyneema fibres under low-velocity impact. Experiments using a Rosand Precision Impact Tester were conducted to analyze deflection and force transmission, while AUTODYN simulations were used to replicate and validate the physical results. The simulations employ advanced anisotropic constitutive models coupled with non-linear equations of state to capture the directional behavior of polymeric matrix composites under transient dynamic loads. Emphasis is placed on the interplay between through-thickness and in-plane material responses, including delamination, matrix cracking, and punching shear. The study demonstrates how hydrodynamic modeling, combined with parametric calibration of shape and stiffness coefficients, can accurately replicate the dynamic deformation behavior of laminated composite systems and guide optimized laminate design for impact resistance.
