Elastic Modulus Of Rubber And Aluminium

Modulus of elasticity is an important design factor for metals for calculations of elastic deflections.

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. Actually elasticity modulus of aluminium is around 69 gpa 10 0 10 6 psi. Young s modulus or the young modulus is a mechanical property that measures the stiffness of a solid material. But the concept was.

Compression modulus is 2 greater than tension modulus. A spring is an example of an elastic object when stretched it exerts a. 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. A stiffer material will have a higher elastic modulus.

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. 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. Elasticity is a property of an object or material indicating how it will restore it to its original shape after distortion. Young s modulus modulus of elasticity of aluminum alloys.

Young s modulus is named after the 19th century british scientist thomas young. 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.

Where stress is the force causing the deformation divided by. 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. Typical young s modulus values of various aluminum alloys are given in the following chart. 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.

The method that have been used to measure modulus of elasticity are following.
