AbstractThis paper presents an evaluation of the elastic properties of titanium foams by two methods: the evaluation of the unloading slopes measured during destructive compression tests and the measurements of the resonance frequencies of foams using laser ultrasound. The results show that the elastic moduli evolve during the compression tests. The values extrapolated at zero defonnation can be used to determine the elastic properties of undeformed specimens. Besicles, laser-ultrasound technique can be used to bring foam specimens into resonance and to measure the elastic modulus and Poisson's ratio. The values measured by the two methods are in good agreement.
