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. 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. A stiffer material will have a higher elastic modulus. 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.
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. And is calculated using the formula below. Young s modulus is named after the 19th century british scientist thomas young. Modulus of elasticity is an important design factor for metals for calculations of elastic deflections.
Typical young s modulus values of various aluminum alloys are given in the following chart. 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. 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 or the young modulus is a mechanical property that measures the stiffness of a solid material. The elastic modulus of an object is defined as the slope of its stress strain curve in the elastic deformation region. Given values are average of tension and compression moduli. 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.
Compression modulus is 2 greater than tension modulus. 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. A spring is an example of an elastic object when stretched it exerts a. Actually elasticity modulus of aluminium is around 69 gpa 10 0 10 6 psi.
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.
