What is Young's Modulus

Youngs modulus the Young modulus or the modulus of elasticity in tension or compression ie negative tension is a mechanical property that measures the tensile or compressive stiffness of a solid material when the force is applied lengthwise. Its pretty important for materials scientists too so in this article Im going to explain what elasticity means how to calculate Youngs modulus and why stiffness is so important.

Shear modulus Youngs modulus and bulk modulus are modulii of elasticity all based on Hookes law and connected to each other via equations.

. The Youngs Modulus of a material is a fundamental property of every material that cannot be changed. The following equations demonstrate the relationship between the different elastic constants where. Youngs modulus is a crucial mechanical property in engineering as it defines the stiffness of a material and tells us how much it will deform for an applie.

Youngs modulus is a measure of the. Let us learn the interesting concept. Youngs modulus numerical constant named for the 18th-century English physician and physicist Thomas Young that describes the elastic properties of a solid undergoing tension or compression in only one direction as in the case of a metal rod that after being stretched or compressed lengthwise returns to its original length.

This tells us that the relation between the longitudinal strain and the stress that causes it is linear. T o C 59T o F - 32. In other words it is how easily it is bended or stretched.

The Youngs Modulus or Elastic Modulus is in essence the stiffness of a material. E Youngs Modulus also known as Modulus of Elasticity. But it also common practice to state it as the ratio of two length units - like mm.

It is often referred to simply as the elastic modulus. Youngs modulus is a measure of a solids stiffness or linear resistance to deformation. Note that strain is a dimensionless unit since it is the ratio of two lengths.

It is defined as the ratio of tensile stress to tensile strain. Youngs modulus can be used to predict the elongation or compression of an object. When a stretching force tensile force is applied to an object it extends and its behavior can be obtained using stress-strain curve in the elastic deformation region known as Hookes Law.

Calculate Youngs Modulus from the Shear Modulus. Y σ ε Mglπr 2 change in l. In this article we will discuss its concept and Youngs Modulus Formula with examples.

The elastic moduli Youngs Modulus Shear modulus and Poissons ratio and damping of copper alloys for example when estimating the stretching of wires under load can be accurately characterized by the non-destructive Sonelastic Systems testing at room temperature as well as at low and high temperatures. Characteristics of Youngs Modulus. The Youngs modulus of steel also referred to as modulus of elasticity of steel is between 190 210 GPa at room temperature which is around 27500 ksi to 31200 ksi.

Youngs modulus or modulus of elasticity is a property of a material that tells us how difficult it is to stretch or compress the material in a given axis. E Youngs modulus Modulus of Elasticity Pa Nm 2 psi lb f in 2 Youngs modulus can be used to predict the elongation or compression of an object when exposed to a force. The Youngs Modulus of the material of the experimental wire is given by the formula specified below.

Youngs Modulus is also known as tensile modulus elastic modulus or modulus of elasticity and its SI unit is Pascal Pa. It is dependent upon temperature and pressure however. The steel young modulus is a measure of its stiffness resistance elastic deformation to tensile loads.

Youngs modulusthe most common type of elastic modulus seems to be the most important material property for mechanical engineers. Calculate Bulk Modulus from the Shear Modulus. However this linear relation stops when we apply enough stress to.

Therefore we can write it as the quotient of both terms. Modulus of Elasticity for some common metals at various temperatures according ASME B311-1995. It quantifies the relationship between tensilecompressive stress force per unit area and axial strain proportional deformation in.

Knowing when an item or material will bend or break is one of the most critical tests in engineering and the characteristic that informs us this is Youngs modulus. Youngs Modulus or Elastic Modulus or Tensile Modulus is the measurement of mechanical properties of linear elastic solids like rods wires etc. Youngs modulus E describes tensile and compressive elasticity or the tendency of an object to deform along an axis when opposing forces are applied along that axis.

Calculate Youngs Modulus from the Bulk Modulus.
