Analogia tarczowo-płytowa w teorii dźwigarów siatkowych

The paper discusses the plate analogy for a discretized mode! as well as for a continuous model of plane surface lattice structures. Such an analogy consists in the similarity of displacement equations describing the state due to the loading acting in the plane of the system, and the stress equations describing the state produced by the loading acting perpendicularly to the plate, as well as in the similarity between the stress equations for the second case. The analogy discussed in the paper may be applied in experimental investigations of stresses occurring in lattice plates.
