The modulus of elasticity of steel is many times higher than that of rubber. Your email address will not be published. By understanding the modulus of elasticity of steel, we can claim that steel is more rigid in nature than wood or polystyrene, as its tendency to experience deformation under applied load is less. In the experimental work the recycle aggregate is used in place of natural aggregate in the proportion of 0,25,50,75 and 100% with and without incorporation of steel fibers. So the unit of Modulus of Elasticity is same as of Stress, and it is Pascal (Pa). This is because it tells us about the body’s ability to resist deformation on the application of force. The modulus of elasticity of steel is the ratio of stress to strain of steel. There are other numbers that give us a measure of elastic properties of a material, like Bulk modulus and shear modulus, but the value of Young’s Modulus is most commonly used.
