  • Within the framework of hydrodynamic-elastoplastic model, equations were established to characterize the response behaviors of aluminum foam under explosive impact.In order to solve the equations, the equations were transformed into discrete Lagrange difference forms in uniform grid.The numerical calculation method was programmed and applied to one-dimensional numerical calculation of underwater explosion and shock response of Al foam in the water.A good agreement is achieved between the numerical calculation, experiment data and results simulated by LS-DYNA-3D, which varified the feasibility of the proposed methodologies to be applied to describe the behaviors of Al foam under explosive impact.The thickness of foam material shell has great impact on the pressure field of underwater explosion.
