This project is focused on the development of a new integrated multi-scale approach incorporating modeling and experimentation on sintering-induced deformation processes taking into account anisotropy phenomena. The project includes the study of the complex interplay between processing conditions and anisotropic microstructure-constitutive properties which will provide fundamental, basic knowledge and a novel practical approach to design and optimize the manufacturing of advanced ceramic and metal systems with programmable macroscopic characteristics and microstructure. This research intends to establish a new methodology to optimize the sintering of a broad range of complex material systems including multilayered solid oxide fuel cells. The developed concepts can be used to design the processing of other multilayered material systems (e.g. sensors, actuators, solar cell packaging) or processing under applied stresses (e.g. hot-pressing, sinter-forging). The project also contributes to the general framework of processing approaches which are enhanced by experimentally validated simulations and which significantly accelerate the development of new materials and processes. The teams from the two universities will work closely with collaborators from the industry to continuously test and refine the simulation approaches.
