Abstract
Plywood plates are usually constructed so that the grain of adjacent plies is perpendicular. Such laminated plates possess two perpendicular axes of elastic symmetry. In this discussion plywood plates having other than 90 degree angles between the grain of adjacent plies are considered. First, a two-ply plate with the grain of one ply making any arbitrary angle with the grain of the other ply is discussed. It is shown that this plate, when in a state of plane stress or when subjected to small deflections, possesses the same two perpendicular axes of elastic symmetry. By making use of the formulas obtained for the two-ply plate, it is shown how to construct a plate of any number of plies (the adjacent plies not necessarily having their grain perpendicular) possessing the same type of elastic symmetry as the two-ply plate.
