CNRS research associate
As micromachined commercial products with mechanical features today exploit only the integration capabilities microfabrication technologies allow (for mass-production of reliable products), there is room for innovative products making the most of micrometer-sized objects, which are very specific from the mechanical point of view for two reasons:
\- Their surface/volume ratio is much larger than for the objects mechanical engineers are used to deal with. The consequence is that strong surface couplings have been evidenced, translating changes in the (electro-)chemical environment into mechanical deformation.
\- the geometric margins (compared to the dimensions) and the material homogeneity resulting from the usual processing techniques are very poor.
As a consequence, studying the mechanical behavior of micrometer-sized objects requires to overcome two main barriers:
\- To identify material constitutive laws at the micrometer scale and to quantify the role of the environment on the behavior;
\- To model chemo-mechanical couplings when materials are heterogeneous and structures are poorly defined.
Moving forward along these two lines requires the development of a dedicated instrumentation and the use of identification techniques suited both to the available experimental data and to the proposed mechanical descriptions.
Chargé de recherches CNRS.
Les objets mécaniques de dimensions micrométriques (MEMS) se distinguent, du fait de leurs faibles dimensions, par deux caractéristiques :
-un rapport surface / volume extrêmement élevé, en comparaison des structures usuelles de la mécanique, de sorte que l'on a pu mettre en évidence des couplages forts, surfaciques, entre mécanique et environnement (chimique ou électro-chimique) ;
\- les tolérances géométriques et l'homogénéité des matériaux employés sont très mauvaises, du fait des procédés d'obtention.
Par conséquent, étudier le comportement mécanique de ces objets micrométriques impose de relever deux défis majeurs :
\- Caractériser le comportement des matériaux à l'échelle micrométrique et quantifier l'influence de l'environnement ;
\- Comprendre et exploiter les couplages mécanique-environnement d'intérêt quand les matériaux sont hétérogènes et les structures sont mal définies .
