Modulus of elasticity (MOE) testing Technically its a measurement of the ratio of stress placed upon the wood compared to the strain (deformation) that the wood exhibits along its length. In the simplest terms, the modulus of elasticity (MOE) measures a woods stiffness, and is a good overall indicator of its strength. Youngs Modulus or Elastic Modulus or Tensile Modulus, is the measurement of mechanical properties of linear elastic solids like rods, wires, etc. The Youngs modulus of elasticity is the elastic modulus for tensile and compressive stress in the linear elasticity regime of a uniaxial deformation and is usually assessed by tensile tests.
