Study on the impact performance of sandwich hollow cylinders hitting water based on SPH method
TL;DR: In this paper, the impact performances of one monolithic cylinder and two sandwich cylinders during water entry are investigated by SPH method, which is validated by an existing experiment. And the authors show that the stress levels and deformations of the cylinders are closely related to the impact forces and their inherent strengths and stiffnesses.
