Kopiika S. Forecasting the strength and the service life of deep-sea ship’s buoyancy constructions

The object is design method for blocks of buoyancy; the purpose is the rise of efficiency of the use of buoyancy blocks of deep-sea hardware; methods are the physical and mathematical modelling of objects of research, statistical methods at experimental researches; the newness in the dissertation is the model of prognostication of tensile strength of block of buoyancy at the hydrostatical compression by recommendation of material composition is first developed, the physically grounded models of volume of damages of buoyancy blocks are built, the decision of task of distribution of spherical dynamic wave in an array for construction of physical model of destruction is used; the results of the research have been results - the methods of computation of possible exploration depth, coefficient of strong reserve and resource of work of buoyancy constructions are developed; the results have been introduced into the buoyancy blocks production; the branch is shipbuilding.
