Elastic properties of plywood panels are essential for predicting
structural behavior of wood systems. The ASTM Standard D 3043-76
which evaluates the moduli of elasticity (MOE) of plywood, treats
these panels as one dimensional beams instead of two-dimensional
plates, which results in an overestimate of the MOE. Improved procedures
for...
Current compression perpendicular-to-grain (c-perp) design values for wood members are based on mean stress using the ASTM D143 specimen. Base design value, as determined from 0.04-in deformation in the ASTM specimen, is applied to all c-perp applications. While the standard ASTM test was presumably believed to adequately reflect relevant c-perp...

The compressive behavior of continuous fiber composites is not as well
understood as their tensile behavior because research and industrial applications have until
recently focused on the latter. Furthermore, most theoretical and experimental studies on
the compression of composites have examined the case of unidirectional specimens with
fibers along the...
