Struts of Minimum Weight

Aircraft Engineering and Aerospace Technology, 1956
IT is intended to show in this article the magnitude of the weight saving which can be achieved on simple struts. It is necessary for any comparison to derive the weight and shape of the solid or hollow strut theoretically most efficient. This can be done most conveniently using the Calculus of Variations and it will be assumed in all cases that the ...

Design for Minimum Weight

Aircraft Engineering and Aerospace Technology, 1960
A new approach to the problem of minimum‐weight design of stiffened compression panels is presented. It is predominantly based on the plate instability mode in which the sheet and stiffeners, having been stressed to the same degree, simultaneously buckle over a long wavelength with the length of a buckle equal to the pin‐ended length of a panel. Charts

Minimum Weight Design of Cylindrical Shells

Journal of Applied Mechanics, 1956
Abstract The theory of collapse and minimum weight design of cylindrical shells by Onat and Prager is applied in this paper to the development of a method for designing the variable wall thickness of a cylindrical shell under axial loading and arbitrary pressures to give maximum economy of material. The design is such that the shell does

Minimum Cost Versus Minimum Weight of Prestressed Slabs

Journal of the Structural Division, 1976
It is found that for a wide range of unit costs of formwork both approaches lead to approximately similar results provided the unit cost ratio of concrete to steel is above 60 (where cost of concrete is per cubic yard and steel per pound). However, if a cost ratio much below 60 prevails, substantial savings can be achieved by using a minimum cost ...
