[P110] Predicting Thermal Expansion Properties of Complex Composite Materials Using Multi-Scale Simulation

Keywords:Multi-scale simulation、Thermal expansion coefficient (CTE)、Finite element method (FEM)、High-entropy ceramics (HEC)、Metal matrix

Multi-scale simulations predict high-temp composite expansion. FEM and thermo-elastic models align. Mo at 2000 K and Nb at 2500-3000 K show highest CTE mismatch and stress, ideal for high-temp use.
