The PI Laboratory has maintained a continuing interest in the development of satisfactory test methods for determining shear characteristics of wood, plywood, adhesives, and more recently sandwich constructions. The anisotropic structure of wood has added to the difficulty of developing test methods that reliably evaluate the desired properties. This paper presents a brief description of the test methods used, traces …
