Wang, S. and Guedes Soares, C. (2017) , “Hydroelastic effects on slamming loads and dynamic response of flexible panels”, Progress in the Analysis and Design of Marine Structures, Guedes Soares, C. & Garbatov Y. (Eds.), Taylor & Francis Group, London, UK, pp. 59-67
Hydroelastic water impacts of panels with different deadrise angles (10º and 30º,), entry velocities (1m/s, 3m/s, 6m/s and 8m/s), plate thicknesses (5mm, 8mm and 11mm), and edge boundary conditions are simulated by using the finite element method implemented in LS-DYNA. To quantify the hydroelastic effects, the results of the slamming loads and maximum deflections from the fully coupled ALE/FEM method in LS-DYNA are compared with the calculations from the quasi-rigid/dynamic analyses. For the fully coupled ALE/FEM method, a multi-material arbitrary Lagrangian-Eulerian (ALE) and a penalty based coupling algorithm are applied for the interaction between the fluids and structures. The governing equations are solved using the finite element method based on explicit time integration schemes. For the quasi-rigid/dynamic analysis method, the slamming loads on the rigid structures are firstly assessed by using LS-DYNA, and then the predicted loads are exerted on the elastic structures to conduct the dynamic analysis.
