متن کاملOptimal thickness distributions of aeroelastic flapping shells
Optimal thickness distributions of aeroelastic flapping shells" (2013). a r t i c l e i n f o a b s t r a c t The severe weight limitations of flapping wing micro air vehicles necessitates the use of thin flexible wings, which in turn requires an aeroelastic modeling tool for proper numerical characterization. Furthermore, due to the unconventional nature of these vehicles, wing design guidelin...
متن کاملOptimal Design of Cylindrical Shells
The present paper studies an optimization problem of dynamically loaded cylindrical tubes. This is a problem of linear elasticity theory. As we search for the optimal thickness of the tube which minimizes the displacement under forces, this is a problem of shape optimization. The mathematical model is given by a differential equation (ODE and PDE, respectively); the mechanical problem is descri...

translation as a comunicative process is always said to be associated with various aspects of meaning loss or gain. subtitling as a mode of translating, due to special discoursal and textual conditions imposed upon it, is believed to be an obvious case of this loss or gain. presenting the spoken sound track of a film in writing and synchronizing the perception of this text by the viewers with...
15 صفحه اولOptimal design of shells with FE based parameterization
In a finite element (FE) based parameterization, data of the FE mesh are used as design variables, such as nodal coordinates and nodal thickness. During shape and thickness optimization, this approach provides much design freedom for a limited modeling effort. Stress results are, however, very sensitive to the local shape changes that can occur during FE based optimization. When stress results ...
