Abstract : Starting with an integral representation of the mechanical behavior there is developed a variational principle concerned with velocities in the quasi-static deformations of a linear viscoelastic body. A functional of the second degree which represents, according to the previous work based on model representation, the elastic energy stored in the body enters the present variational principle in a natural manner.
