Title: Numerical Simulation of Blast-resistant Performance of Aluminum Foam Sandwich Structures and Optimization
Abstract: The blast-resistant performance of six types of sandwich panels were analyzed by using dynamic finite element method and compared in deforming,motion and energy absorption responses. It is founded that the sandwich structure consisting of aluminum panel,aluminum foam and high strength armor steel panel is much better than others under blast loading,and the density of the core of aluminum foam influences the dynamic responses of sandwich structure greatly. A dynamic finite element model for optimal design is established,and the thicknesses of metal panels and the aluminum foam core layer are optimized by using adaptive response surface method. The results show that the blast-resistant capability of aluminum foam sandwich structure increases remarkably.
