Direct Stresses in Cylindrical Shells,on that through every point of the cylinder one may pass a straight line which lies entirely on this surface. These lines are called the generators. For convenience of language we shall assume here that the generators are horizontal. All planes which are normal to the generators intersect the cylind

Bending Stresses in Shells of Revolution, of shells were treated: The angle . between the meridian and an arbitrary datum meridian, and the colatitude ø (figs. II-1 and II-2). For the derivatives with respect to these coordinates we shall use the dash-and-dot notation explained on p. 88.

ell roofs or pressure vessels, and consider all the minor details of stress calculations and even the design. On the other hand, he might stress the mathematical side of the subject to such an extent that he virtually writes a book on differential equations under the guise of the mechanical subject.

Buckling of Shells,thods of the theory of elastic stability must be applied: the method of adjacent equilibrium or the energy method. We shall explain here the basic ideas of both methods in the terminology of shells and then consider an . column to demonstrate their use simply.

General Properties of Stress Systems in Shells,fines a cross section and then calculates the resultant of the stresses acting in it. Instead of describing this resultant by its magnitude, direction and location in space, he usually gives its three components and its moments about three axes. These quantities, commonly known as the normal force,
