4. Conclusions Numerical simulation of deformation and fracture in aluminum – boron carbide composite at the microlevel was carried out. Analysis of the calculation results allows us to draw the following conclusions: 1. During cooling of the composite the matrix material located at a certain distance from the ceramic particle experiences volumetric tensile loads, while the regions directly adjacent to the particle are weakly deformed or compressed. 2. Under external tension or compression cracks in particles propagate in different directions: perpendicular or along the loading direction, respectively. 3. Residual thermal stresses increase the tensile strength of the composite and lead to a change in the fracture mechanisms from in-particle cracking to debonding.

(3) was developed according to the Government research assignment for ISPMS SB RAS. References Balokhonov, R., Romanova, V., Schmauder, S., Emelianova, E., 2019.
