# Grids and plates.

Thirty demonstrations illustrate the behavior of structures consisting primarily of grids of beams and flat or folded plates. Shows load-carrying mechanisms of grids and plates, including load-carrying capacity due to the stretching of their middle plane through membrane stresses. Offers examples of actual flat, ribbed, and folded plate structures. From the Mechanics of Structures and Materials series Summary/ip>Robert A Heller presents experiments which show how grids and plates in structures react under various kinds of stresses.
