In this study, the aggregate model is randomly generated by Monte Carlo method, and there is the possibility that the particle size distribution of a single model is uneven.
Therefore, four sets of microscopic finite element models are established for each operating condition to eliminate random deviations and verify the universality of the models.
Average the results of multiple models to effectively reduce the impact of randomness on simulation conclusions, ensuring the reproducibility and reliability of the results.
As shown in Figure 2.
9, the stress-strain curves of different models are highly consistent, indicating that the three-dimensional microscopic finite element model established in this paper has good consistency.
