## Wood elasticity chart

stress is proportional to strain to the proportional limit (throughout the elastic deformation). The slope of Rheology: If wood is under a constant load, it will continue to deflect further with time. See Table A.5. on Page 515-523 in the Textbook  For larger forces, the graph is curved but the deformation is still elastic— \Delta L will return to (a) By how much does the wood flex perpendicular to its length?

The following table is Structural Lumber Wood Engineering Properties. Modulus of Elasticity of Wood, Wood Engineering Design Data. Modulus of elasticity also referred to as Tensile Modulus or Young's Modulus. Elastic ratios for various wood species at approximately 12% moisture content - see bottom of webpage. Related Lumber Wood Engineering Data: Modulus of elasticity ratings are derived from the stiffness or resistence to bending of the particular wood species. These ratings pertain to longitudinal modulus of elasticity, not tangential or radial ratings. This chart is showing the stiffness or MOE, modulus of elasticity of all wood species used in flooring and decking applications. Modulus of Elasticity (MOE) Ratings for All Species (1000 psi) Modulus of elasticity ratings are derived from the stiffness or resistence to bending of the particular wood species. These ratings pertain to YOUNG'S MODULUS (MODULUS OF ELASTICITY) OF WOOD. Average Young's modulus values of wood along the longitudinal axis (E L) obtained from bending tests are given in the following table. Mechanical Properties of Wood David W. Green, Jerrold E. Winandy, and David E. Kretschmann Contents Orthotropic Nature of Wood 4–1 Elastic Properties 4–2 Modulus of Elasticity 4–2 Poisson’s Ratio 4–2 Modulus of Rigidity 4–3 Strength Properties 4–3 Common Properties 4–3 Less Common Properties 4–24 Vibration Properties 4–25 Modulus of elasticity or Young's modulus is the ratio of stress to strain. Within the elastic range below the proportional limit, this ratio is a constant for a given piece of wood, making it useful in static bending tests for determining the relative stiffness of a board. Wood strength, including the relationship between grain direction and strength, specific gravity as an indication of wood strength, and additional ways to measure wood strength. Part of the Workshop Companion, a collection of information on wood, woodwork, woodworking skills, woodworking materials, and woodworking plans that together form the core knowledge needed by woodworkers, furniture

## The table below provides laboratory-derived values for several mechanical properties of wood that are associated with wood strength. Note that due to sampling inadequacies, these values may not necessarily represent average species characteristics.

Young's Modulus or Tensile Modulus alt. Modulus of Elasticity - and Ultimate Tensile and Yield Strength for steel, glass, wood and other common materials. Sponsored Links. Tensile Modulus - or Young's Modulus alt. Modulus of Elasticity - is a measure of stiffness of an elastic material. It is used to describe the elastic properties of objects Wood Screws - Withdrawal Forces - Allowable withdrawal load force; Wood Species - Moisture Content and Weight - Weight of green and air-dried fire wood; Wood, Panel and Structural Timber Products - Mechanical Properties - Density, fibre stress, compressive strength and modulus of elasticity of clear wood, panel and structural timber products The strength of wood increases with a reduction in the moisture content. Reference design values for sawn lumber assume maximum moisture content of 19%. Wood with a moisture content of 19% or less is considered dry. Kiln dried or seasoned wood would be considered dry as long as it hasn’t been exposed to weather long enough to cause re-saturation. products, ASTM D 3043 for structural wood-based panels, ASTM D 5456 for structural composite lumber products, General Technical Report FPL–GTR–190 Table 12–1.
