Abstract : The purpose of this study was to evaluate the potential of materials with negative Poisson's ratio ('auxetic' materials) for application in hydroacoustics. The results of the literature search were collected in this report in order to facilitate the task of anyone who would like to become familiar with this subject. For an isotropic material, the upper bound of Poisson's ratio v is 1/2. This bound is closely approximated by soft elastomers. It is energetically possible for a isotrophic material to have a negative Poisson's ratio, with a lower bound of -1. K.E. Evans has proposed the designation 'auxetic' for such materials, derived from the Greek word auxesis, which in biology is used for 'increase of cell size without cell division'. The bibliography is preceded by comments that are divided into sections parallel to the headings in the list of works. The categorized listing of the literature follows an alphabetic listing of the complete set. It does not appear that thus far auxetic materials have found applications in hydroacoustics that are drastically different from those obtained by means of the more common materials. ...
