Toward a homogenizing machine

Résumé

The idea of an experimental homogenization device adapted to the case of architectural materials is discussed here. Although more advanced homog-enization schemes exist, the case of average-field homogenization by KUBC within the framework of linear elasticity is studied here because of its (rel-ative!) simplicity of adaptation to an experimental setup. The main idea here is to propose a device that is simple to implement, inexpensive but that allows to apply a load as close as possible to a perfect KUBC thanks to the use of pantographs to distribute the displacements on the edges of the specimen. For the purposes of the design and tests-design, a reduced model of the device has been developed.
