Hexapod for 3D X-ray tomography imaging
Description
This mechanical testing device is designed to deform porous architectural materials (cellular materials, fibrous materials, lattice networks, etc…) of milli- to centimetric sizes, in order to study their mechanical behavior under multi-axial loading, i.e., by subjecting the samples to the relative movement of the hexapod jaws with simple or complex kinematics according to the three possible translations and rotations. The system is designed for insertion into X-ray microtomographs (synchrotron or laboratory sources). As a result, it will be possible to make in situ, or even real-time, 3D observations of the mesostructures of these materials during loading, in order to analyze their deformation mechanisms. These tests will a priori be carried out at room temperature.
