  • 15. MODULUS OF ELASTICITY

    Chapter 15 –Modulus of Elasticity page 79 15. MODULUS OF ELASTICITY The modulus of elasticity (= Young's modulus) E is a material property, that describes its stiffness and is therefore one of the most important properties of solid materials. Mechanical deformation puts energy into a material. The energy is stored elastically or dissipated

    May 30, 2017 · It depends upon the definition of 'Elastic'. If by elastic you mean more stretchable then 'NO'. The best example is a rubber band. For a small load you can stretch it a long way, but if you increase the load it will tear. On the other hand for a s...

  • Young's Modulus - an overview | ScienceDirect Topics

    Young's modulus, also referred to as elastic modulus, tensile modulus, or modulus of elasticity in tension is the ratio of stress-to-strain and is equal to the slope of a stress–strain diagram for the material. In the standard test method, ASTM D412, a force is applied to a .

  • What is a Flexural Modulus? - Definition from Corrosionpedia

    It is fundamentally equivalent to the elastic modulus of a material, which is a measure of a material's elasticity, but the two properties commonly hold different values, particularly in polymeric materials. Flexural modulus is tested from a 3-point analysis on a rectangular beam of .
