Web1. The young's modulus is like the 'spring constant' for a material. It comes from treating the atoms in a material as harmonic oscillators. It is a material property that does not depend on geometry. The young's modulus for both of the materials you mention is equal. Now the stress they feel will be different under the same applied load. Share. WebThe Bulk modulus is the ratio of volumetric or bulk stress to volumetric or bulk strain, represented by K and mathematically given by-. K = σ ϵ v. Substituting. ϵ v = 3 σ Y [ 1 − 2 m] in above equation we get-. K = σ 3 σ Y [ 1 − 2 m] ⇒ K = Y 3 [ 1 − 2 m] Hope you understood the relation and conversion between Young’s modulus and ...
