Question

Define young's modulus y, bulk modulus k and poisson's ratio

Answer 1

The relationships between the elastic constants are. E = 2 G ( 1 + v ) a n d E = 3 K ( 1 − 2 v ) Poisson's ratio v being defined as the ratio of lateral strain to longitudinal strain and bulk modulus K as the ratio of volumetric stress to volumetric strain.
