Abstract:
Based on the structure characteristic of plywood and former predictions of in-plane modulus of poplar veneer, the stiffness models of classical laminate plate theory were applied to plywood. In the models test, two plies impregnated paper were orthotropicly overlaided on the face and back poplar veneer. When the test specimens were under single axial tensile load or pure bending moment load, the strain of face and back plies, ε x and ε y was obtained through strain gage. The experimental and theoretic value of some compliance coefficients were tested. The results showed that the stiffness models could predict the stiffness of plywood well, and the stiffness models of classical laminate plate theory could be used to describe the stiffness of plywood.
