Young's modulus (or modulus of elasticity): Young's modulus of steel at room temperature is ordinarily between 190 GPA (27500 KSI) and 215 GPA (31200). Tensile elasticity indicates the ability of a body to undergo linear deformation. A solid material is called elastic if it is able to naturally return to its original shape after the applied loads are removed. The modulus of elasticity is the measure of the elastic deformation of the material under force. Chai Hao. GN/m 2 or kN/mm 2. Modulus of elasticity (or also referred to as Young’s modulus) is the ratio of stress to strain in elastic range of deformation. Even though, the units of Young’s modulus are Pascal, it is not widely used. Young’s modulus is named after the 19th-century British scientist Thomas Young. Young's modulus, E, is the most important of the elastic constants and can be derived from the slope of the strain–stress curve obtained when a rock specimen is subjected to unconfined compression (i.e., static loading), it being the ratio of stress to strain.The strains are measured by attaching strain gauges to the test specimens, or by displacement transducers, and recording their outputs. Wrought iron. Elastic modulus is an intrinsic material property and fundamentally related to atomic bonding. The shear modulus, or the modulus of rigidity, is derived from the torsion of a cylindrical test piece. Therefore, unit of an elastic modulus is the same as the unit of stress, i.e., pressure unit (Pa, kPa, MPa, GPa, psi, ksi, etc.) Young’s Modulus in Linear Elasticity. The energy is stored elastically or dissipated plastically. On the other hand, if the ratio between stress and strain is constant during the deformation process, then Young’s modulus is also a constant, and the material is considered to be linear elastic. This is a very useful parameter in material science. Hardness is an engineering property and for some materials it can be related to yield strength. With the compressive strength test on the concrete specimen (cylinder of 15 cm diameter and 30 cm length having a volume 15 cm cube), the modulus of elasticity of concrete is calculated with the help of stress and strain graph. Stress is applied to force per unit area, and strain is proportional change in length. University. Please sign in or register to post comments. Comments.
