Shear Modulus is generally denoted with a letter C. Bulk Modulus is generally denoted with the letter K.ДЄlso known as Rigidity Modulus, the ratio of the tangential force applied per unit area to the angular deformation in radians is called the shear modulus. Thus, when a body is subjected to three mutually perpendicular stresses of the same intensity, the ratio of direct stress to the corresponding volumetric strain is what we call the Bulk Modulus. The ratio of the stress applied to the body on the body's fractional decrease in volume is called the bulk modulus. The ratio proportion of the longitudinal strain to the longitudinal stress is known as Young's modulus. Following are the different types of modulus of elasticity: The modulus of elasticity of a material is the quantification of its stiffness and for most materials remains consistent over a range of stress. For example, in the graph below, the modulus is reported as stress at different levels for various materials. In the case of synthetic polymers having elastic properties like rubber, the modulus is simply expressed as a measure of the force at a given elongation. In contrast to brittle materials like metals and plastics, elastomeric materials do not display a yield point and continue to deform the material body elastically until they break. Note: Brittle materials such as plastics, aluminium, copper and composites will reveal a steeper slope and higher modulus value than ductile materials such as iron, rubber, steel, etc. A huge steel specimen will have a similar modulus as a small steel specimen, though the large specimen would need a greater maximum force to deform the material. Seeing that both stress and strain are normalized quantifications, modulus exhibits a consistent material property that can be differentiated between specimens of different sizes. In this, the stress (Пѓ) is force divided by the specimen's cross-sectional region and strain (Оµ) is the alteration in the length of the material divided by the material's original measure length. Focusing on the elastic region, if the slope is between two stress-strain points, the modulus will be the change in stress divided by the change in strain.

Graphically, a Modulus is described as being the slope of the straight-line part of stress, denoted by (Пѓ), and strain, denoted by (Оµ), curve. Graphical Representation of What is Modulus of Elasticity After undergoing the elastic region and through their production point, materials enter a plastic region, where they reveal everlasting deformation even after the tensile stress is removed.

The stress induces them to deform, but the material will resume to its earlier state after the stress is eliminated. When under stress, materials will primarily expose their elastic properties. Modulus of elasticity measures the resistance of a material to non-permanent or elastic deformation when a ratio of the stress is applied to its body. Modulus of Elasticity also referred to as Elastic Modulus or just Modulus is the quantification of the ratio of a material's elasticity.
