Impact of an elastic spherical shell on a thin fluid layer

摘要: The axisymmetric problem of the impact a spherical shell on thin layer an ideal incompressible fluid is considered. strains are described by means normal mode method, decomposition flow zone onto subzones proposed in [1] being used for hydrodynamic analysis and determination radius wetted surface. connected hydroelasticity reduced to evolutionary system differential equations calculations features carried various parameters problem. It shown that vibrations corresponding higher modes develop lower part during This agreement with experiments proves inconsistency models which few number taken into account. thinner layer, loads amplitude elastic impact.
