Numerical modeling of the low-velocity impact of composite plates using a shell-based SPH method

Abstract : This paper investigates the numerical modeling of low velocity impact of composite multilayered plates using the smoothed particle hydrodynamics (SPH) method. Recently the authors developed a shell-based SPH (SSPH) model for the modeling of large deformations of composite multilayered structures, has been extended to the impact modeling. The proposed new shell-based SPH formulation is based on the Mindlin–Reissner theory which accounts for transverse shearing stresses. In the present investigation, the impact modeling solution is estimated using the explicit dynamics integration scheme, together with the Hertzian contact theory, for the fast estimation of contact forces. The predictive capability of the present SSPH model is demonstrated by comparison of the results with reference solutions for the impact response of composite multilayered plates
