In this paper the nano conical shell model is developed based on modified strain gradient theory. The governing equations of the nano truncated conical shell are derived using the FSDT, and the size parameters through modified strain gradient theory have been taken into account. Hamilton’s principle is used to obtain the governing equations, and the shell’s equations of motion are derived with ...

We develop a general setting for N = 2 rigid supersymmetric field theories with gauged central charge in harmonic superspace. We consider those N = 2 multiplets which have a finite number of off-shell components and exist off shell owing to a non-trivial central charge. This class includes, in particular, the hypermultiplet with central charge and various versions of the vector-tensor multiplet...

This review paper aims to present an updated review of papers, conference papers, books, dissertations dealing with nonlinear vibrations of circular cylindrical thin shells. This paper surveyed mathematically, experimentally, analytically, numerically analyzed vibrations of cylindrical shells. This includes shells of open type, closed type, with and without fluid interactions; shells subjected ...

Phellandrenes are naturally occurring cyclic dienes belonging to monoterpene class and have many medicinal applications. In the present study, some resonance stabilized radicals from α- β-phellandrene also closed shell structures those been investigated within constraints of density functional theory basis set employed. For structure optimizations closed-shell open-shell structures, B3LYP/6-311...

Plates and shells represent principal elements of aerospace structures, including fuselages of planes and missiles, control surfaces, bulkheads, helicopter blades, and others. The multiple applications, shapes, and materials found in plate and shell structures dictate the necessity of a comprehensive approach to their analysis reflected in relevant theories and methodologies. Various aspects of...

curls and curves of a shell interweave its various strain modes and link them together. this interactional behavior has yet frustrated all attempts for the construction of shell templates, which needs for an individual element test in traditional approaches. such a test fails to work for shell elements and must be reconstructed. in this paper, it is tried to study shell interactional behavior a...
