What are mechanical properties of wood?

The mechanical properties of wood include strength in tension and compression (as measured in axial and transverse directions), shear, cleavage, hardness, static bending, and shock (impact bending and toughness).

What is Poisson’s ratio for wood?

Poisson’s ratio relates the strain parallel to an applied stress to the accom panying strain occurring laterally. For wood, the six Poisson’s ratios are denoted µLR, µLT, µRT, µTL, and µTL.

What are the 12 properties of wood?

The main physical properties of wood include: color, luster, texture, macro-structure, odor, moisture, shrinkage, internal stresses, swelling, cracking, warping, density, sound – electro – thermal conductivity.

How is structural steel made in EN 10025?

The EN 10025 structural steel grades are all readily weldable by means of the usual metal arc processes. Steel making Steel is manufactured via the basic oxygen furnaces (BOF). All steel is desulphurised to maintain a high degree of cleanliness and is made fully killed and fine-grained from continuously cast slabs.

What’s the difference between EN 10025 and N condition?

N condition refers to both normalising rolling and normalising. The grade designations of EN 10025 refer to the minimum yield strength of each grade for thicknesses less than or equal to 16mm. Above 16mm, the yield strength decreases as the thickness increments increase.

What does the suffix ar mean in EN 10025?

The suffix AR refers to the As-rolled condition. If the material is normalised then the indication ‘+N’ will appear as a suffix. The EN 10025 structural steel grades are all readily weldable by means of the usual metal arc processes. Steel making Steel is manufactured via the basic oxygen furnaces (BOF).

What’s the minimum yield stress for stainless steel?

European standard that specifies the tolerances for hot rolled plates of non-alloy and alloy steels, including stainless steels of the following properties: Nominal width equal to or greater than 600 mm. Specified minimum yield stress less than 700 N/mm 2.
