In a recent experimental study [6] X ray microtomography has been used to visualize
and describe the behavior of these materials during uniaxial loading and confined compression.
Pressure tank Balance Sample Steel ballast Figure 2 : Hydrostatic compression test This test has been developed for materials with density lower than 1000 kg/m3 but can be adapted to materials with higher specific gravity.
The global behavior of the materials can be characterized by a first linear elastic response, where the bulk modulus of the material is identified (2.9 GPa), and the collapse pressure (95 MPa), called "crush pressure".
It can be noted (Figure 4a) that the initial bulk modulus of the two materials is comparable and that the crush pressure of the material with rigid matrix is significantly higher than for the material with the soft matrix (90 MPa compared to 50 MPa).
