Abstract

The aim of the paper is to find a parametrical representation for the constitutive laws for which the motion equations can be associated to a pseudospherical surface with negative Gaussian curvature K. These constitutive laws suggest the existence of a Tzitzeica surface for which the ratio K/d4 is constant, where d is the distance from the origin to the tangent plane at an arbitrary point.
