Sommario/riassunto |
|
This book presents the idea of zero-range potentials and shows the limitations of the point models used in structural mechanics. It also offers specific examples from the theory of generalized functions, regularization of super-singular integral equations and other specifics of the boundary value problems for partial differential operators of the fourth order. <br><i>Contents:</i><ul><li>Vibrations of Thin Elastic Plates and Classical Point Models</li><li>Operator Methods in Diffraction</li><li>Generalized Point Models</li><li>Discussions and Recommendations for Future Research</li></ul><br>< |
