Elastic Modulus Of Rubber And Aluminium

Young s modulus e or y is a measure of a solid s stiffness or resistance to elastic deformation under load.

Elastic modulus of rubber and aluminium.

And is calculated using the formula below. Young s modulus is named after the 19th century british scientist thomas young. Young s modulus or the young modulus is a mechanical property that measures the stiffness of a solid material. An elastic modulus also known as modulus of elasticity is a quantity that measures an object or substance s resistance to being deformed elastically i e non permanently when a stress is applied to it.

Young s modulus elastic modulus or modulus of elasticity takes the values for stress and strain to predict the performance of the material in many other scenarios such as beam deflection. The elastic modulus of an object is 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. Elastic moduli 2 1 ν e g 3 1 2ν e k for polycrystalline solids as a rough guide poisson s ratio 3 1 ν shear modulus g e 8 3 bulk modulus k e these approximations break down for rubber and porous solids.

It relates stress force per unit area to strain proportional deformation along an axis or line the basic principle is that a material undergoes elastic deformation when it is compressed or extended returning to its original shape when the load is removed. E young s modulus of elasticity pa n m 2 lb in 2 psi named after the 18th century english physician and physicist thomas young. Elasticity is a property of an object or material indicating how it will restore it to its original shape after distortion. Typical young s modulus values of various aluminum alloys are given in the following chart.

But the concept was. A stiffer material will have a higher elastic modulus. Given values are average of tension and compression moduli. The method that have been used to measure modulus of elasticity are following.

Compression modulus is 2 greater than tension modulus. Young s modulus modulus of elasticity of aluminum alloys. A spring is an example of an elastic object when stretched it exerts a. Where stress is the force causing the deformation divided by.

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.
