Impact and Indentation Behavior of Sandwich Panels

Modeling and Experimental Testing

Lindholm, Carl-Johan

Abstract The behavior of sandwich panels subjected to local loads and low-velocity impact is studied with analytical and numerical methods as well as quasi-static testing and low-sped impact testing. The results indicate that the core thickness has no influence on the initial part of the indentation behavior for a panel if the core thickness is larger than a certain critical core thickness. Both the analytical model and the numerical calculations agreed well with both the quasi-static testing and the low-velocity impact test.
