Mechanical properties
Wood is a composite material
In order to measure the wood mechanical features, we need to consider its moisture and density content.
Under the same moisture content, the elastic module ranges from 9 to 15.5 MPa for Hardwoods and between 7 and 14 MPa for the soft ones.
Its tensile strength is between 100-120 MPa along the fibres whereas it is 10-20 times less along their orthogonal direction.
Generally speaking, the tensile strength is 2 or 3 times higher than the compression-traction.
The nodes can diminish the toughness of wood and alter its mechanical features. However, this material is as resistant as fiber-reinforced composites against breaks when stressed along the fibres.
