Introduction, be collected as a set of differential equations or as an energy principle. The simultaneous satisfaction of each component of the elasticity problem often is foreboding from the mathematical standpoint; therefore, engineers have naturally looked to simplifications and approximations.

Conclusion,plex structures is relegated to the domain of numerical analysis, and several citations to the literature in this area were provided. Although the calculations for those situations may be more involved, such structures generally reflect the same basic behavioral characteristics as the relatively simple illustrations contained in this book.

Introduction,onents of the elasticity problem are often designated as ., ., and a .. The equilibrium equations represent a statement of Newton’s laws, which are restricted here to the static case. The compatibility conditions express the kinematic relationships between strains and displacements, and the constitu

Membrane Theory,ons are coupled only through the transverse shear stress resultants, .. and .. If we suppose that for a certain class of shells, the stress couples are an order of magnitude smaller than the extensional and in-place shear stress resultants, we may deduce from equations (3.22a-c) that the transverse
