available surface qualities. s (ii) for wisa birch special bb (iii) and wg (iv) for wisa birch. all available surface qualitieds comply with the en 635 standard (plywood classification by surface appearance) and are in part stricter. s and bb are for end use where sound surface appearance is required. wg is recommended for applications where the technical properties of birch plywood are needed but surface appearance is not of primary importance.【Get Price】

shear modulus wikipedia

the shear modulus is concerned with the deformation of a solid when it experiences a force parallel to one of its surfaces while its opposite face experiences an opposing force (such as friction). in the of an object shaped like a rectangular prism, it will deform into a parallelepiped. anisotropic materials such as wood, paper and also essentially all single crystals exhibit differing material response to stress or strain when tested in different directions. in this case, one may need to 【Get Price】

bulk modulus wikipedia

where ρ is density and dp/dρ denotes the derivative of pressure with respect to density (i.e. pressure rate of change with volume). the inverse of the bulk modulus gives a substance's compressibility. other moduli describe the material's response (strain) to other kinds of stress: the shear modulus describes the response to shear, and young's modulus describes the response to linear stress. for a fluid, only the bulk modulus is meaningful. for an anisotropic solid such as wood or paper&nbsp;【Get Price】
