Abstract

It is common engineering practice in a hydraulic model study involving both gravity waves and a solid structure to measure the hydrodynamic forces on the model of the structure and then calculate the resulting internal structural stresses. Because of the large variety of available elastic material, and the latest development in solid state physics, it is now feasible to measure directly these structural stresses in a scale model study. It is shown how the similitude of elastic force s in structure s subjected to wave action can b e made compatible with the Froude similitude valid for hydraulic motion. Several examples are presented to illustrate the method . These include the study of the elastic response of an ice floe, the motion of an underwater membrane-type oil storage tank, the behavior of the Mohole riser, and the motion of a Texas Tower type of structure under wave action. Results obtained in the NESCO wave tank are also presented.
