Poisson's ratio for wood southern pine
WebMechanical Properties of Wood - Conrad Forest Products WebJun 7, 2010 · Typically, the Mod. of Rupture will be 8 to 10 times the allowable stress, depending on wood species and moisture level. For shear, a good value for ultimate strength is even more elusive. Probably the best available is "Shear Strength Parallel to Grain". Again, this is based on small-scale tests under optimum conditions.

WebPoisson's ratios and Young's moduli were measured for five sugar pine (Pinus lambertiana Douglas) boards in a plane delineated by the grain direction and a tangent to the growth … WebE value or modulus of elasticity of the individual elements. E is a ratio that relates the amount a given load causes a material to deform. A material with a higher E value is stiffer. For example: No.2 grade eastern white pine has an E value of 1,100,000 and No.2 hem-fir has an E value of 1,300,000. Hem-fir is a stiffer material.
