Professor Barry Bernstein is interested in the mechanical and thermodynamic behavior of materials. This behavior is important in material processing problems, such as those that occur in the extrusion and molding of polymers. Professor Bernstein is well known for his part in the formulation of a widely used mathematical model for behavior of polymer melts and bulk polymers. This model is known as the BKZ (Bernstein, Kearsley and Zapas) constitutive equations, in which the ideas of finite elastic strain are incorporated into a theory of fluids. The formulation treats the thermodynamics as well as the mechanics of such media.
He has also done computational work on polymeric fluid flows and is in part responsible for a finite element formulation known as flucode. In the past, Professor Bernstein also worked on tracer analysis of blood circulation and of recycle reactors.
