Although the viability of this method has been demonstrated several times, we may point out some limitations involved with such measurements. On fibre reinforced composite systems the use of SPATE has so far been limited to simple comparative studies or to qualitative NDT-type applications. This is probably due to the lack of an adequate theory which describes the thermoelastic process for a general laminated composite structure and to the essentially different damage behaviour between isotropic and anisotropic multiphase materials. A numerical mo
