  In the course linear elastic material, in the lecture Generalised Hooke’s law-lesson 3 by Mr Bhargava Systa sir when defining stress as function of strain the formula given is
  
  Kindly check the formula and confirm whether it is correct or not.
  In my opinion as ε_xy, ε_yz , & ε_zx are representing true strain, in R.H.S in strain matrix in place of ε_xy it should be 2ε_xy , in place of ε_yz it should be 2ε_yz , in place of ε_zx it should be 2ε_zx .
