Abstract: By means of a suitable change of variables we obtain, by application of a general result by Dafermos and Hsiao, cf. [2], an existence theorem in $ {L^\infty } \cap {BV_{loc}}$ of a weak solution of the system corresponding to the quasilinear hyperbolic equation

$\displaystyle {\phi _{tt}} - p'\left( {\phi _x} \right){\phi _{xx}} + {\phi _t}... ...\qquad in \qquad \mathbb{R} \times \left[ {0, + \infty } \left[ \right. \right.$

, for small initial data in BV. This theorem is a partial extension of Dafermos's result for the case with $ F\left( \phi \right) \equiv 0$, proved in [1].
