Young s modulus or the young modulus is a mechanical property that measures the stiffness of a solid material.
Elastic modulus of rubber.
Young modulus for rubber.
Rubber elasticity refers to a property of crosslinked rubber.
Elastomers have played a key role in the development of new technologies in the.
Silicones are polymers with a si o si backbone.
Tensile modulus or young s modulus alt.
Modulus of elasticity is a measure of stiffness of an elastic material.
In an application that requires a rubber seal to be stretched into place a low modulus compound might be considered to make assembly easier.
Tensile modulus is defined as the.
There are different types depending on functional groups in the structure and curing mechanisms.
This can be repeated many times with no apparent degradation to the rubber.
You will see this on a physical property data sheet written something like modulus 100 elongation.
Rubber elasticity arises from the orientation of chain segments and the degree of this orientation underlies the mechanical properties.
But the concept was.
Ut tensio sic vis latin sentence from robert hooke 1678 means such extension such strength proportionality rule.
Where stress is the force causing the deformation divided by the area to which the force is applied and strain is the ratio of the change in some length parameter caused by the deformation to the original value of the length parameter.
The modulus of elasticity also known as the elastic modulus the tensile modulus or young s modulus defined as the slope of its stress strain curve in the elastic deformation region.
It defines the relationship between stress force per unit area and strain proportional deformation in a material in the linear elasticity regime of a uniaxial deformation.
Rubber has a low young s modulus of 0 01 to 0 1 gpa as it is highly elastic.
It can be stretched by up to a factor of 10 from its original length and when released returns very nearly to its original length.
Elongation is proportional to applied strength.
Main applications are flexible seals o rings etc.
Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and technological importance.
It s the measure of the stiffness of the material.
Gruand méca sarl cy for his redaction.
Carbyne has the highest known young s modulus of 32100 gpa meaning it is the least elastic or most rigid material known at the moment.
Diamond has a high young s modulus of 1050 1200 gpa as it is highly rigid.
Young s modulus is named after the 19th century british scientist thomas young.
Key properties include thermal stability chemical stability electrical insulation and low toxicity.
The most facile way to quantify the orientation is from the optical birefringence defined as the difference in refractive indices for two perpendicular directions.
It is used to describe the elastic properties of objects like wires rods or columns when they are stretched or compressed.
