Failure Modes of Foam Core Sandwich Beams under Static and Impact Loads
TLDR
In this article, the authors describe the use of sandwich structures in load bearing structures due to their high specific stiffness and high specific strength, such as the ones used in this paper.Abstract:
In recent times, sandwich structures have been widely used in load bearing structures due to their high specific stiffness and high specific strength. Some sandwich structures, such as those used i...read more
