The compression modulus is about 2% higher than the tensile modulus (Youngâs modulus). MODULUS OF ELASTICITY The modulus of elasticity (= Youngâs modulus) E is a material property, that describes its stiffness and is therefore one of the most important properties of solid materials. elastic modulus; Hyponyms Post author By mansadevi; Post date October 12, 2020; Bulk modulus is defined as the ratio of pressure applied to the corresponding decrease in â¦ It is defined as the ratio of pressure increase to relative volume decrease. Poissonâs ratio is the ratio between the lateral strain and the linear strain and is said to be a constant for a given material. K = E / 3 (1 - 2 r) (1) where . Mechanical deformation puts energy into a material. Bulk Modulus Of Elasticity Today we will look at the interesting topics in physics that are bulk modulus. The proportional region, within the elastic limit of the stress-strain curve (region OA in the above figure), is of utmost importance for both structural and manufacturing engineering designs. Bulk Modulus is related to Modulus of Elasticity and Poisson's Ratio as.
