What is the relationship between energy release rate and fracture toughness (SIF) in 3D?

  Hello
  
  I hope you are doing well. My query is what is the relationship between energy release rate (G) and Stress intensity factor (K) in 3D? The relationship is as shown below https://en.wikipedia.org/wiki/Energy_release_rate_(fracture_mechanics).
  G=k1^2/E for plane stress
  and
  G=(k1^2)*(1-nu^2)/E for plane strain
  where E and nu are modulus of elasticity and Poisson ratio
  But all these relations are only for plane stress or plane strain. What is the relationship for 3D problems? I am very confused. Please help.
