Wood composites are traditionally modeled as orthotropic solids.
Laminated veneer lumber (LVL) is an engineered wood composite
manufactured by laminating thin wood veneers that are
arranged parallel to the length of the material and boned using
adhesive. LVL is commonly used in wood construction as headers,
beams and flange materials of prefabricated I-joists. It is also used
as window and door frames
