5.4 (b)  Relationship between  EY, g, m=G and k  (Cont'd)

Previous: 5.4 Relationships Between Ey, g, m = G and k

Consider a simple shear state

 

Consider hydrostatic stress state

k = Bulk modulus=

 

For interrelationship, see table (below)

 

        Note: For isotropic materials, there are only 2 constants (engineering) 

or Lame ( )
