| Sep 28, 2021 at 14:25 | comment | added | NMech | @HarshitRajput wood is quite difficult to tell with regard to the elastic modulus because its basically made from cellulose. The big difference in the wood example is in strength. However elasticity is also significantly affected but its better evidenced when different material of different moduli are the constituents of the composite material. | |

So is it like, if we have a prismatic bar made of wood, and if we apply load along longitudinal direction, the ratio of stress and strain in this direction (which is E) will be different than the ratio of stress and strain, if we were to load it perpendicular to the longitudinal axis (in simple tension). | |

| Sep 28, 2021 at 13:48 | comment | added | alephzero | Modulus of elasticity does have a direction! For example the modulus of wood is very different along the grain and perpendicular to the grain. A single crystal of a substance is both a pure substance and homogeneous, but most crystalline materials are not isotropic. For a general anisotropic material there are 21 different independent elastic moduli, not just two (i.e. Young's modulus and Poisson's ratio), | |
