Application of a variational method to the vertical hydrodynamic impact of axisymmetric bodies

▸ A desingularized variational numerical method is presented to treat the hydrodynamic impact problem. ▸ Trial functions are constructed from elementary potential solutions. ▸ An integral measurement for the boundary condition error contained in the weak solution is proposed. ▸ Added mass calculation follows a Rayleigh-like quotient scheme leading to second order errors results.
