Modulus of Rupture The Wood Database Modulus of Rupture, frequently abbreviated as MOR, sometimes referred to as bending strength , is a measure of a specimen’s strength before rupture. 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. That is to say, some species of wood will bow under stress, but not easily break.
