Since stiffened plates are typical structures in ships, studying the impact of underwater explosions with different types of explosives on ships is of great significance. This experiment investigated the damage characteristics of blasting, shaped, and linear shaped charges on the same type of stiffened plate. The experimental results indicate that linear shaped charges can create larger penetration holes on target plates, but they suffer from insufficient flight capability. In contrast, shaped charges exhibit stronger penetrating power, yet they lack sufficient damage capability against target plates. Although the penetration capability of blasting charges is inferior to the first two, its overall deflection of the plate frame exceeds that caused by shaped charges and linear shaped charges by 1.6 % and 5.7 %, respectively. To further investigate the penetration process and the load characteristics of the penetrator, a finite element model was established in this paper.

However, previous studies have been insufficiently comprehensive in exploring energy absorption performance and other related aspects. Given the superior mechanical properties of Triply Periodic Minimal Surface (TPMS) structures, four different types of hybrid TPMS structures were designed and fabricated by fused deposition modeling (FDM) process. Quasi-static and dynamic experiments were conducted to investigate their mechanical response and deformation behavior under compression, with a focus on the impact of relative density, loading directions and loading speeds. Meanwhile, numerical simulations were supplemented according to the experimental arrangement to uncover mesoscopic information that cannot be directly obtained from experiments. The experimental and numerical results demonstrated that the hybrid structures exhibited distinct properties depending on the loading direction. As the relative density increased, the plateau stress of the hybrid structures increased significantly, while the deformation mode remained nearly unchanged. Compared to specimens compressed along the lateral direction, the hybrid structures subjected to axial loading presented higher plateau stress due to their uniform deformation. Additionally, the hybrid design mitigated the stress softening phenomenon in the post-yield response of TPMS structures. Notably, the hybrid TPMS structures demonstrated superior specific energy absorption (SEA) and energy absorption efficiency compared to uniform structures, with SEA shows an improvement of 15 % to 59 % compared to the uniform Gyroid structure, and an improvement of 5.6 % to 72.4 % compared to the uniform Diamond structure.
