Elastic Modulus

The modulus of elasticity measures the force necessary to tension a material specimen and extend it to a given percentage of its original size.

Modulus of Elasticity

The modulus of elasticity measures the force necessary to tension a material specimen and extend it to a given percentage of its original size.

Normally the test evaluates the modulus of elasticity at 50% (the force necessary to extend the specimen by 50% of its original size), at 100% and at 300%.

The higher the value measured during the tensile test, the better the material characteristics. In the field of seals, a high modulus of elasticity is preferable, as it ensures a high lip force against the mating surfaces, both in dynamic and static sealing, and a higher resistance to extrusion.

As shown in the diagram at right, under tension (elongation) the elastic deformation that the test material can undergo without suffering breaking or irreversible effects is understood. Elongation is a parameter inversely proportional to the material hardness.

This modulus is a key indicator both for the seal toughness and its resistance to extrusion.

The modulus is measured by calculating the stress and dividing it by the elongation, that is, stress units divided by elongation units.

Ultimate tensile stress (toughness), is calculated by measuring the force required by a specimen to exceed the elastic phase and tear or break, thus taking an irreversible shape.
