Descripción del proyecto
Nuevas soluciones para el problema del diseño de materiales
Una nueva oportunidad se consolida para los metamateriales, gracias a los progresos en fabricación aditiva (FA) y las técnicas de impresión 3D. A pesar de las impresionantes propiedades que poseen los metamateriales (ligereza, rigidez y solidez), la mayoría de estos materiales avanzados se han diseñado sin tener en cuenta los límites de fabricación. Por ejemplo, muestran señales de debilidad o una resistencia limitada. Para resolver estas limitaciones, el proyecto financiado con fondos europeos MADAM incorporará propiedades de resistencia y fabricación en el proceso de diseño de materiales. En concreto, el proyecto desarrollará algoritmos numéricos para resolver los problemas de diseño que surgen cuando se consideran los límites de la FA, así como las limitaciones por estrés.
Objetivo
This projects aims to develop numerical algorithms for designing the new generation of advanced materials: Metamaterials. Their impressive properties (one of the lightest, stiffest and strongest materials available today) arise from their non intuitive topologies. Due to the additive manufacturing (AM) revolution or 3D-printing techniques, we are at the right moment where these complex topologies are now possible to be created.
However, additive manufacturing has its own manufacturability constraints. Although several advances have been developed in the last years, most of these new advanced materials, specially mechanical metamaterials, have been designed with considering no manufacturability constraints, i.e. are just theoretically design. Even more worrying, when manufacturability is possible, they show severe symptoms of fragility or limited resistance. MADAM project seeks to solve these limitations incorporating manufacturability and resistance properties in the process of material design (MAD).
The specific objectives are:
1) Develop numerical algorithms to solve the MAD problem when considering AM constraints.
2) Develop numerical algorithms to solve the MAD problem when considering stress constraints.
3) Develop second order optimization algorithms to efficiently solve the MAD problem.
The project is throughly designed for maximizing training and transfer of knowledge to the host. Risk and project management, IPR and Communication activities are also meticulously designed.
Additionally, MADAM will be connected with the enormous multi-partner AM Sofia consortium (Michelin, EADS) by disseminating and attending (confirmed) to monthly industrial meetings. My supervisor’s experience, the full assistance of his group, CMAP scientific knowledge and Ecole Polytechnique resources are the perfect instruments for developing the MADAM project.
