Dynamic Failure Analysis of Aluminum Foam Sandwich Structure Using 3D Material Point Method

Abstract:

Article Preview

The blast-resistant of an aluminum foam sandwich structure under impact has been investigated. Plastic deformation and load distributions in each of the sub-layers during and after impact were calculated by the material point method with the consideration of strain rate effect on deformation of the aluminum foam. The numerical results from the 3D material point method modeling show that the blast-resistant capability of the aluminum foam sandwich structure is excellent, and the energy absorbability of the structure would be underestimated if the strain rate effect on the aluminum foam is ignored.
