Rubber is a member of a larger class of materials called elastomers and it is difficult to overestimate their economic and technological importance.
Elastic modulus of rubber.
Thomas young his british fellow countryman will leave his name associated to this linear behavior of many materials.
You will see this on a physical property data sheet written something like modulus 100 elongation.
Young s modulus is named after the 19th century british scientist thomas young.
Main applications are flexible seals o rings etc.
Elastomers have played a key role in the development of new technologies in the.
Modulus of elasticity is a measure of stiffness of an elastic material.
Ut tensio sic vis latin sentence from robert hooke 1678 means such extension such strength proportionality rule.
Tensile modulus or young s modulus alt.
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.
Silicones are polymers with a si o si backbone.
Key properties include thermal stability chemical stability electrical insulation and low toxicity.
Rubber has a low young s modulus of 0 01 to 0 1 gpa as it is highly elastic.
Diamond has a high young s modulus of 1050 1200 gpa as it is highly rigid.
Young s modulus or the young modulus is a mechanical property that measures the stiffness of a solid material.
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.
But the concept was.
Young s modulus is also known as tensile modulus elastic modulus and modulus of elasticity measure of elasticity.
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.
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.
It s the measure of the stiffness of the material.
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.
While modulus and durometer are somewhat related there can be a pretty large variance in modulus values between two compounds of the same durometer.
It is used to describe the elastic properties of objects like wires rods or columns when they are stretched or compressed.
Tensile modulus is defined as the.
Rubber elasticity refers to a property of crosslinked rubber.
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.
Gruand méca sarl cy for his redaction.
Rubber elasticity arises from the orientation of chain segments and the degree of this orientation underlies the mechanical properties.
The most facile way to quantify the orientation is from the optical birefringence defined as the difference in refractive indices for two perpendicular directions.
