Does anyone have the mechanical properties on Norway Maple? I am looking for shear strength, bend modulus, tensile strength, compressive strength and so on . Every chart I look at lists sugar maple, red maple, black maple, silver maple, bigleaf maple, but never Norway maple. Norway Maple is becoming more and more common in the northeast USA because it is invasive and fast growing and is now beginning to crowd out the sugar maples, yet no-one I ask knows a thing about it. Someone please enlighten me.

Dan,
Check the USFS forest products labratory website. There are located in Madison, wi. They have those properties for just about any species youu can imagine.
Hope that helps.

I just spoke with someone from the USFS and unfortunately they have no information about this species.
From contributor Qu
That is too bad.

Are Norway and Red maple not the same ?Have been led(mis?) to believe so in the past .
From contributor Da
Red Maple is Acer-rubrum and Norway Maple is Acer_platanoides

Dan,
Seeing as the norway maple is in the hard maple family. I would use the wood properties from the hard maple family.
Like sugar or black maple. Properties are going to be pretty close.

Being a norwegian woodworker this thread caught my attention . Here is the mechanical principles for different wood species used up in here. Maple "lønn" is listed, guess its norwegian. You also have different tables with other types of properties on the left hand side. The info is from a organisation or guild for broadleaf sawmills. Hope google translate can help or that you can figure it out.

Mechanical Properties
Average values ​​of mechanical properties in at Norwegian deciduous tree species.
Values ​​are based on surveys of F. Kollmann, Chr. Scheiber and Wagenführ R., B. Kucera, L. Nagode and M. Foslie.
The values ​​are valid for small clear specimens and must not be used in structural designs.
More on this topic in the book: Wood - nature's most beautiful raw materials, published on Landbruksforlaget 1999, ISBN 82-529-2167-1
In all four tables tells about different mechanical properties.

Bending strength shows the load a beam can withstand before it breaks. Static bending strength is one of the most important properties of wood.
Modulus of bending expresses try play's resistance to being deformed.
Tensile strength parallel to the fibers expressing sample workpiece resistance to destruction by pressure or shear zones and is an important indicator of the strength of the wood.
Compressive strength expresses try play's resistance to compression ..

Shear strength parallel to the fibers is the shear stress leading to displacement / fracture between two parallel layers in the sample.
Torsjonsfashet expresses try play's resistance to being deformed by torsion.
Impact fracture work expresses the timber's ability to withstand shock loads.

Hardness is the tree's ability to provide resistance to penetration by a hard body. This property is of great importance that require high wear resistance.
Column tension shows wood's resistance to cleavage / cleavage.

Nail tension shows wood's ability to provide resistance to extraction of the nail. Normally, nail strength substantially greater across the grain than in the fiber direction.
Screw tension shows wood's ability to provide resistance to extraction by screw. Turn resistance is usually somewhat larger in the radial direction than in tangentialretningen.
