Rolling Shear Modulus of Sweetgum Plywood and Unidirectionally Laminated Veneer

Evangelos J. Biblis

Abstract


Experimentally obtained values of apparent rolling shear modulus and strength of sweetgum 4-ply, 12.7-mm-thick plywood, when the shear forces are applied parallel to the face grain of the plywood, are presented. Also presented are experimental values of true rolling shear modulus (GTR) of unidi-rectionally laminated sweetgum veneer tested in the dry condition. Finally, the experimentally obtained value of the apparent rolling shear modulus of the tested sweetgum plywood was closely predicted using the obtained GTR and GLR values.
