Bogdan D. The identification of pulse loading acting on elastic plates and half-space

The object of research is the constructive elements in the form of circular, rectangular plates on elastic foundation and half-space. The aim of the research is to design methods of non-stationary loadings identification and to create oscillatory control algorithms. The methods of research are Laplace and Hankel transformations, methods of Volterra integral equations solving, Tihonov's regularization method. Theoretical importance of the work results consist in design methods of new inverse problems solving in theory of plates on elastic foundation and half-space. Practical importance of the results obtained in dissertation consists in possibility of their use to determine non-stationary loads indifferent engineering process based on impulsive energy sources use. The scientific novelty is a) for the first time the inverse problems for rectangular, circular and infinite plates on elastic foundation were solved; b) for the first time the method of identification of circular plate loading space-time dependence was created; c) for the first time the method of half-space boundary displacements identification was created. The results of dissertation was applied during the economical contract fulfillment. The dissertation results were applied during the contract concluded between KNAHU and METENERGOMASH fulfillment. The sphere of the dissertation result usage also include technological process based on impulse material treatment.
