A semi-analytical model of hydroelastic slamming

A semi-analytical model of hydroelastic slamming for two-dimensional symmetric flexible bodies is presented in this paper. The hydrodynamic loads are computed using the analytical Modified Logvinovich Model (MLM) with account elastic deflections body surface. described by modal approach. rigid and motions at same time together wetted part coupled problem impact reduced to a system nonlinear ordinary differential equations, which integrated implicit Newmark method iterations each step. Both free fall constant water entry cases considered. developed validated wedge cylindrical shell problems. Good agreements existing experimental numerical results achieved. It shown that MLM significantly improves predictions stresses cause compared Wagner impact. suitable efficient accurate computations impacts.
