Abstract : By the term 'discrete method' of plate and shell design is understood a numerical method which leads to a discrete solution, in particular the differential-difference method or the 'straight-line' method. Earlier-developed discrete methods dealt with simple cases of plate and shell design. In this article it is shown that a discrete method can be generalized in a simple way for more complex problems in the mechanics of thin-walled structures (e.g., bending of a flexible plate, strength of an orthotropic, noncircular, cylindrical shell), and the final integro-differential equations obtained can be solved by successive approximations utilizing a discrete solution of a simple analogous problem as the zero approximation.
