Lecture 25 :


$\displaystyle \sigma = -pI^{*} + \mu'(\nabla\,.\,\vec{V})+ 2\mu (Def \,\,\vec{V})^{**}$ (25.7)

  • The specific forms for different coordinate systems can easily be obtained from Eq. (25.7).
    In a cartesian coordinate system,



    This is known as deformation tensor . Note that is a symmetric tensor
