Structural response of laminated composite plates to blast load |
Dolce Ferdinando - Italian Air Force (Italy) |
Abstract |
This work deals with three-dimensional numerical simulations of damage caused by air blast on fully clamped rectangular plates. The study examines the performance of both metallic and CFRP laminates subjected to blast loads using commercial LS-DYNA software, including a cohesive damage model to represent delamination. The blast load was simulated using a CONWEP algorithm and MMALE approach with fluid–structure interaction between the Eulerian blast and Lagrangian target models. The simulation results are presented and compared with the experimental data, showing good agreement in terms of dynamic deflection, damage morphology and residual deformation.
