Fig. 2. Numerical stress-strain curve of the three-phase composite.

Also, notice that the matrix of the composite material (Al 2 O 3 ) fractures due to the criterion based on the tensile pressure, while the fracture of inclusions occurs when the criterion based on the accumulated inelastic strain is fulfilled.
