Abstract : The authors consider a onedimensional mathematical model problem for the motion of a viscoelastic material with fading memory governed by the quasilinear hyperbolic integrodifferential equation of Volterra type. For given Cauchy data they use the method of vanishing viscosity and techniques of compensated compactness to obtain the existence of a weak solution (in the class of bounded measurable functions) in a special case. (Keywords: a prior estimates; Equations of motion).
