A composite-circle model was adopted for analytical modeling. Model microstructures consisting of square-array, hexagon-array, and brick wall-array of grains with an intergranular phase as well as an actual microstructure of random-array grains with an intergranular phase were adopted for numerical simulations. The results showed that in predicting CTEs, the simple analytical model represents the two-dimensional composite well except that with brick wall-array grains, which induced significant anisotropic CTEs in the composite. The residual thermal stresses in composites were also discussed.[SDGs]SDG11journal article10.1023/A:10048904153162-s2.0-0035121302https://www2.scopus.com/inward/record.uri?eid=2-s2.0-0035121302&doi=10.1023%2fA%3a1004890415316&partnerID=40&md5=394c6bb32405439a55302f5bb8a9cf95
