Preface

This work is devoted to an updated exploratory survey of results concerning elastic cusped shells, plates, and beams and cusped prismatic shell-fluid interaction problems. It also contains some up to now non-published results and new problems to be investigated. Mathematically, the corresponding problems lead to nonclassical, in general, boundary value and initial-boundary value problems for governing degenerate elliptic and hyperbolic systems in static and dynamical cases, respectively. Two principally different approaches of investigation are used: (1) to get results for 2D (two-dimensional) and 1D (one-dimensional) problems from results of the corresponding 3D (three-dimensional) problems and (2) to investigate directly governing degenerate and singular systems of 2D and 1D problems. In both the cases, it is important to study the relationship of 2D and 1D problems with 3D problems. On the one hand, it turned out that the second approach allows to investigate such 2D and 1D problems whose corresponding 3D problems are not possible to study within the framework of the 3D model of the theory of elasticity. On the other hand, the second approach is historically approved, since first the 1D and 2D models were created and only then the 3D model was constructed. Hence, the second approach gives a good chance for the further development (generalization) of the 3D model. The present work is addressed to engineers interested in the mathematical aspects of practical problems and mathematicians interested in engineering applications. Both can find new challenging pr
