Abstract: One-dimensional (1D) analytical model and finite element (FE) simulation are employed to investigate the shock mitigation capability of stepwise graded cellular claddings to underwater blast. To build the analytical model, two types of core configurations are considered: (i) “low → high” with the weakest layer being placed at the impinged end and (ii) the “high → low” configuration. Details of fluid–structure interaction (FSI), response of the graded cladding, and the cavitation phenomenon are thoroughly studi…
