Mechanical Properties Of Oak Wood. Oak hardwood has an open and fairly long identifiable grain. Thus the mechanical properties of the clear wood may indicate that a species is an excellent wood for boxes for bulk commodities but the lumber may be unsuited for such use because of a characteristic tendency of the knots to loosen and fall out. PART I THE MECHANICAL PROPERTIES OF WOOD INTRODUCTION The mechanical properties of wood are its fitness and ability to resist applied or external forces. Produces good results with hand and machine tools.

Can react with iron particularly when wet and cause staining and. Air Dry 12-15 Moisture Content Mechanical Properties Metric English Comments. Mechanical properties most commonly measured and represented as strength properties for design include modulus of rupture in bending maximum stress in compression parallel to grain compressive stress perpendicular to grain and shear strength parallel to grain. For construction purposes the physical properties of the wood itself are most pertinent and European oak possesses a number of strengths that make it particularly desirable. Has moderately high shrinkage values resulting in mediocre dimensional stability especially in flatsawn boards.

Bending strength modulus of elasticity in bending compression strength and tensile strength were determined using micro- and standard-size mechanical test samples. Furthermore the advantage of inherently low shrinkage or high nail-holding power in a species may be lost through the. Past investigations have demonstrated that both red oak and white oak wood are hard strong in bending and endwise compression Brown et al. Oak hardwood has an open and fairly long identifiable grain. It is largely such properties that determine the use of wood for structural and building purposes.
