It has the highest tensile strength and a moderately low heat capacity among wood-based materials. Focusing on the elastic region, if the slope is taken between two stress-strain points, the modulus is the change in stress divided by the change in strain. It can be used to determine a wood species' overall strength; unlike the modulus of elasticity, which measures the wood's deflection, but not its ultimate strength. Typical elastic modulus values of predominately granular materials are shown . Modulus of Elasticity. 0.38. The modulus of elasticity of the grain (propellant) is of the order of 1000 psi.
