advantages orthotropic wood

orthotropic material - wikipedia

in material science and solid mechanics, orthotropic materials have material properties that differ along three mutually-orthogonal twofold axes of rotational symmetry. they are a subset of anisotropic materials, because their properties change when measured from different directions. a familiar example of an orthotropic material is wood.【Get Price】
