“…Moreover, strategies that enhance modelling efficiency while ensuring the accuracy of particle shapes must be developed. Currently, research into the morphology of particles with irregular shapes has attracted widespread attention [7][8][9][10][11], given their ubiquitous presence across natural and engineered environments, such as rock debris and granular materials. Extensive studies into the morphological construction and physical attributes of these particles have substantially enhanced our comprehension of their unique properties and behaviours.…”

This study employs the discrete element method to investigate the influence of particle size on the load-bearing characteristics of aggregates, with a specific emphasis on the aggregates used in escape ramp arrester beds. This study utilises the log edge detection algorithm to introduce an innovative approach for modelling irregularly shaped pebbles, integrating their physical properties into a comprehensive discrete element model to enhance the accuracy and applicability of simulations involving such pebbles. Meticulous validation and parameter calibration (friction coefficient: 0.37, maximum RMSE: 3.43) confirm the accuracy of the simulations and facilitate an in-depth examination of the mechanical interactions between aggregate particles at macroscopic and microscopic scales. The findings reveal a significant relationship between the particle size and load-bearing capacity of aggregates. Smaller pebbles, which are more flexible under pressure, can be packed more densely, thereby improving the distribution of vertical forces and increasing the concentration of local stress. This enhancement substantially increases the overall load-bearing capacity of aggregates. These discoveries hold significant implications for engineering practices, particularly in the optimisation of safety for truck escape ramps and in identifying the ideal sizes of pebbles with irregular shapes.

“…However, due to the difficulty in measuring the interface strength, quantitative research on the degradation of interface strength during aging is limited. Representative volume element (RVE)-based [ 17 , 18 , 19 ] mesoscale and microscale models play important roles in studying the multi-scale mechanical properties of PFPCs. In particular, the RVE combined with the cohesive zone model (CZM) [ 20 , 21 , 22 ] has been widely used to simulate particle debonding in PFPCs, which is also named dewetting in some of the literature [ 23 , 24 , 25 ].…”

In this study, the aging performance of particle-filled polymer composites (PFPCs) under thermo-oxidative conditions was investigated on multiple scales. High-temperature-accelerated tests were conducted to analyze the effects of aging time and temperature. A representative volume element (RVE) model was established for the PFPCs using a random particle-filling algorithm. A predictive model for the crosslink density was conducted based on the closed-loop chain reaction of polymer oxidation. According to the theory of polymer physics, the relation between the crosslink density and matrix modulus was determined. The particle/matrix interface in the RVE model was represented by the cohesive zone model (CZM). The parameters of the CZM were determined by the inversion techniques. Then, a comprehensive multiscale RVE model was constructed, which was applied to predict the modulus and dewetting strain of the aged PFPCs. The predicted results show good agreement with the test results, which verifies the reliability of our model.
