A simplified panel model is described, together with a number of assumptions about the mode of its buckling. The approach to the calculation of the buckling stress is by splitting the panel into a number of flat plates and ...

The theory of sandwich construction developed in this paper proceeds from the simple assumption that the filling has only transverse direct and shear stiffnesses, corresponding to its functional requirements. This supposition ...

Summary. A linear programme is formulated which determines the layout and member sizes of frameworks, designed to carry given forces, made from material with a given allowable stress and using a minimum volume of material. ...
