Özet
The linear, three-dimensional interaction problem between an ice sheet and a bottom-mounted vertical circular cylinder subject to a pulsating point source beneath the ice is studied using the vertical mode (VM) method. The water beneath the ice is assumed to be inviscid, incompressible, and of finite depth. The ice sheet is rigidly attached to the cylinder’s surface. No incident waves are present in the system. The fluid motion is described using potential flow theory, while the ice sheet is modeled as an elastic plate of uniform thickness, and its deflection is determined by the Bernoulli–Euler equation. The study examines the hydrodynamic forces on the vertical cylinder, along with the resulting strain distributions and ice deflections in the ice cover, with particular focus on conditions that may affect the structural integrity of the ice cover induced by the oscillating point source. The findings demonstrate a trade-off where increasing ice thickness provides a shielding effect that reduces horizontal loads and strain concentration, while increasing the vertical lifting force due to enhanced flexural rigidity. Based on critical strain limits, the study establishes frequency-dependent safe operating boundaries, specifying safe horizontal distances and submergence depths required to prevent source-induced ice failure.
