AbstractImpact forces between small bodies colliding in a regular wave are estimated using the contact theory of Hertz and an elastoplastic model due to Lankarani and Nikravesh (1994). To determine the relative impact speed, the equations of motion for the bodies on a surface wave are formulated in two dimensions using the methods of Kane and Levinson (1985) and solved numerically. It is assumed that the motion normal to the wave surface is small and can be neglected, i.e. the bodies move along the propagating wave profile. A Stokes second order wave is used and the wave forces are applied using Morison's equation for a body in accelerated flow. Wind loads are similarly modeled using drag coefficients.
