Strength Properties of Wood for Practical Applications ...

Strength properties of wood also can be estimated using the following equation for given moisture content, so that wood can be used with a higher efficiency for any applications: P = P 12 (P 12 / P g) (12-M / Mp–12) Where: P = property value. P 12 = property value at 12 percent moisture content.

Mechanical properties of a balsa wood veneer structural ...

Balsa wood is an appropriate core material for structural sandwich applications due to its high strength- and stiffness-to-weight ratios. However, the mechanical properties vary considerably owing to the inherent scattering of natural wood materials. One approach to reduce this scatter and tailor the mechanical properties according to specific ...
