Elastic Modulus Of Rubber And Aluminium

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.

Elastic modulus of rubber and aluminium. A stiffer material will have a higher elastic modulus. Young s modulus e or y is a measure of a solid s stiffness or resistance to elastic deformation under load. And is calculated using the formula below. 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.

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. Typical young s modulus values of various aluminum alloys are given in the following chart. A spring is an example of an elastic object when stretched it exerts a.

Room temperature modulus of elasticity values for some of the aluminum alloys copper alloys cast irons various non ferrous metals steel alloys and titanium alloys are given in the following chart. Compression modulus is 2 greater than tension modulus. Young s modulus modulus of elasticity of aluminum alloys. 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 method that have been used to measure modulus of elasticity are following. Actually elasticity modulus of aluminium is around 69 gpa 10 0 10 6 psi. 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. Where stress is the force causing the deformation divided by.

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. But the concept was. 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. Modulus of elasticity is an important design factor for metals for calculations of elastic deflections.

Given values are average of tension and compression moduli.
