The flatwise Young's modulus and the flatwise shear modulus of 3-, 5-, and 7-ply plywoods made of Lauan (Shorea sp.) veneers have been determined by conducting flexural vibration tests with various specimen lengths and by finite element analysis. The results indicate that the flatwise Young...

Both shear strengthand modulus of rigidity may be determined. Primarily, the testsmeasure the planar shear (rolling shear) strength developed inthe plane of the panel.1.2 Structural panels in use include plywood, waferboard,oriented strand board, and composites of veneer and ofwood-based layers.1.3...
It differs by 10% from the result of free beam equation (E = 26.8 GPa). If l/h⩾22 was satisfied in free slab, the error of free beam equation would be less than 1% in dynamic elastic modulus calculation of ConclusionsReferences (14) H. Yoshihara Edgewise shear modulus of plywood ...
Developed in the late 1970's and early 1980's at the University of Wyoming, the Iosipescu shear test produces a uniform shear state due to two v-notched grooves in the specimen. This fixture can test the shear strength and modulus of all three stress states, but is limited to either un...
One definition of a fluid is a substance with a shear modulus of zero. Any force deforms its surface. Shear Modulus Equation The shear modulus is determined by measuring the deformation of a solid from applying a force parallel to one surface of a solid, while an opposing force acts on it...
