Derivation of a Viscoelastic Constitutive Model in Curvilinear Coordinates
A virtual work expression in general curvilinear coordinates was developed by Sokolnikoff [31] and can be derived by taking the dot product of the integrand of the stress equilibrium equation with a virtual displacement vector having covariant displacement components and then integrating the expression over the volume.
