Overcoming the current limitations of CMCs in terms of performance, use and market competitivity requires large efforts in two main directions: (i) a better knowledge of the actual capabilities of the existing materials and of the processes for their fabrication, and (ii) the design of new structures and processing routes. For this, modeling activities are a key component of the research & development strategy, attracting wide interest in the CMC community. This symposium is devoted to broad applications of modeling techniques or sets of techniques to high-temperature ceramic matrix composites – their fabrication, structure and organization and behavior in use. Modeling may address any scale from angstrom to meters, ranging from ab-initio and atomistic computations to continuum physics, and any physical phenomenon of interest (principally mechanical, thermal, and chemical) considered alone or coupled together. Nowadays, artificial intelligence (AI) and meta-modeling tools bring new perspectives to tackle the inherent complexity of CMC design. Special attention will be given to experimental verification of models, but papers focused on design and creation of new concepts are also particularly welcomed.
