Elastic Modulus Of Rubber Material

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.

Elastic modulus of rubber material.

Mykin s rn00170 nitrile buna n 70 durometer is a general purpose copolymer of butadiene and acrylonitrile. Tensile modulus is defined as the. Elongation is proportional to applied strength. This is due to nitrile s compatibility with most environments as well as it s relative cost compared to other rubber materials.

The elastic modulus of an object is defined as the slope of its stress strain curve in the elastic deformation region. Ut tensio sic vis latin sentence from robert hooke 1678 means such extension such strength proportionality rule. Displaystyle lambda stackrel text def frac text stress text strain. Key properties include thermal stability chemical stability electrical insulation and low toxicity.

This can be repeated many times with no apparent degradation to the rubber. Young s modulus e is defined as the ratio of the stress applied to the material along the longitudinal axis of the specimen tested and the deformation or strain measured on that same axis. Young s modulus is named after the 19th century british scientist thomas young. Nitrile is the most commonly used rubber material.

Young s modulus is also known as tensile modulus elastic modulus or modulus of elasticity. Main applications are flexible seals o rings etc. There are different types depending on functional groups in the structure and curing mechanisms. Thomas young his british fellow countryman will leave his name associated to this linear behavior of many materials.

Young s modulus or the young modulus is a mechanical property that measures the stiffness of a solid material. But the concept was. This compound has a relatively high acrylo content. λ def stress strain.

Tensile modulus or young s modulus alt. Why does the elastic modulus of rubber increase with temperature. After stretched it relaxes close to if not exactly to its original length. Elasticity is the mechanical property of a material to return to its original shape where tensile set is the amount on extension remaining after being stretched.

A stiffer material will have a higher elastic modulus. Rubber elasticity refers to a property of crosslinked rubber. But i want to know why intuitively elastic modulus should decrease with temperature. A rubber band would have a low tensile set percentage.

Modulus of elasticity is a measure of stiffness of an elastic material. 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 is used to describe the elastic properties of objects like wires rods or columns when they are stretched or compressed. Young modulus for rubber.
