The principles of designing sandwich panels for slamming loads include selecting the correct core materials and understanding the fundamental loading differences between static uniformly distributed pressure loads and slamming induced pressure pulses. This paper will discuss the two issues in detail.

The results demonstrate that the testing method used for characterisation of core materials can have a significant effect on the shear strength obtained, and that slam loaded panels are subjected to higher shear loads relative to bending than is the case for uniform pressure loaded panels. The combination of these factors results in significant performance advantages for high-elongation foam cores in slam loaded hull panels.
