www.fpl.fs.fed.usModulus of rupture—Reflects the maximum load-carrying capacity of a member in bending and is propor-tional to maximum moment borne by the specimen. Modulus of rupture is an accepted criterion of strength, al-though it is not a true stress because the formula by which it is computed is valid only to the elastic limit.

plastics-rubber.basf.comThe modulus of elasticity (E-modulus) is determined by tensile testing according to DIN EN ISO 527-1A, using a test specimen at a testing speed of 1 mm/min. The E-modulus is calculated from the initial slope of the stress-strain curve as ... of rupture of the specimen.

wp.optics.arizona.eduThe modulus of elasticity may also be characterized as the “stiffness” or ... Brittle materials fail due to tensile (normal) stresses and rupture occurs along a surface perpendicular to the load. Ductile materials usually fail on planes that correspond to the maximum shear stresses
