Elasticity implies that deformations produced by low stressbelow the proportional limit are completely recoverableafter loads are removed. When loaded to stress levels abovethe proportional limit, plastic deformation or failure occurs.Typically, the stress–strain curve for wood-based composites is linear below the proportional limit. The slope of thelinear curve is the MOE. In compression or tensile tests, thisslope is sometime referred to …

Strength properties usually reported include modulus of rupture. (MOR, bending strength), compression strength parallel to surface, tension strength parallel to … The term composite is used to describe any wood materialbonded together with adhesives. The current product mixranges from fiberboard to laminated beams and components.In this chapter, wood-based composite materials are classified into the following categories: panel products (plywood,oriented strandboard (OSB), particleboard, fiberboard,medium-density fiberboard (MDF), hardboard); structuraltimber products (glued-laminated …

Abstract There is an increasing …
