... is moving toward the structure. At t = 0, the ice hita the structure. Then, the velocity boundary condition v = 0 can be applied at the ice boundary. As time passes, stresses are generated in the ice, and the velocity changes within the ice. The stre88, strain and damage propagate with the speed of Cd...

... to each of the quasi-linearized initial-value problems are recombined so as to always satisfy the boundary conditions during the iterations. The nonlinear boundary-value problem is then solved by successive iterations similar to the relaxation methods (Press et al., 1986). The algorithm, using the Newton...

... information on maximum deflection , impact duration and maximum impact force. The design formulae are expressed as a function of geometry and material properties of the struck plate, mass and impact velocity of the striking object. The effect of other boundary conditions is also discussed. Key Words: Plate...
