Moisture and temperature become the primary factors contributing to premature degradation of asphalt pavement. In this study, debonding behaviors at asphalt-aggregate interface under coupled moisture conditions have been systematically investigated through molecular dynamics simulations. The cohesive adhesive asphalt-water-aggregate systems are evaluated by tensile test, interaction details between asphalt, water, aggregate characterized. Results show that can synergistically promote...
This study presents a numerical modelling framework based on complex variable meshless methods, which can accurately and efficiently track arbitrary crack paths in two-dimensional linear elastic solids. The key novelty of this work is that the proposed scheme enables direct element-free approximation for solutions fracture mechanics problems. moving least-squares with group simple polynomial basis applied to implement model, problems both stationary or progressive cracks are considered...
Graphene can improve the self-healing properties of asphalt with high durability. However, behaviors graphene-modified nanocomposite and role incorporated graphene are still unclear at this stage. In study, pure investigated through molecular dynamics simulations. Asphalt bulks two crack widths locations for introduced, interactions among components sheet analyzed. The results show that location significantly affects asphalt. near surface greatly accelerate process by interacting aromatic...

One of the most important tasks in numerical analysis fracture problem is to achieve a high-precision approximation singular stress fields at crack tips. Partially or fully enriched basis functions are often used as enhancements on whole domain just near tips when constructing meshless shape simulate singularity tips, namely: global enhancement with basis, partially local and basis. The scheme has been extensively successfully employed handling problems single crack, but its applicability...
Free energy calculation is a challenging problem in molecular dynamics (MD). Its key issue to get entropy. However, entropy seems difficult be obtained by MD directly, but requires support from other methods, such as phonon theory and cluster variation method, etc. In this work, we find way obtain free single task. It derived fluctuation first, then prove that it does not rely on can independent. Finally, use method study Si, the results agreement with experiment.
