As a result, wood possesses material properties that may be significantly different from other materials normally encountered in structural design. sented 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 Arch 172: Properties of Wood Structure and Properties of Wood A Presentation by the Canadian Wood Council and Forintek Canada Corporation Canadian Conseil Wood canadien Council du bois . Ash wood is a common craft wood, and is known for being versatile and relatively strong for its weight. White Ash has excellent shock resistance, and along with hickory (Carya spp.) It has excellent shock resistance and is good for steam bending. However, despite all the benefits of ash, it's not right for every purpose. Ash has a pronounced grain, the sap wood is creamy white the heartwood is a grayish brown the grain is coarse and interlocked. ft.
