“…The simplest model-short-range force-was introduced in [31], and a better description is available in [39,49]. Other contact models and properties are presented in [50][51][52][53]. Two loadings-pressure and shear traction-have been applied to the model.…”

While a shot-range force contact mode is available in Peridigm, it has been implemented only for explicit and not quasi-static simulations and it does not consider contact between nodes that are While a shot-range force contact mode is available in Peridigm, it has been implemented only for explicit and not quasi-static simulations and it does not consider contact between nodes that are While a shot-range force contact mode is available in Peridigm, it has been implemented only for explicit and not quasi-static simulations and it does not consider contact between nodes that are bonded initially.…”

“…At present, numerical simulation has become an efficient solution to study the dynamic effects of railways with the development of computer science [14,15]. Many studies have been conducted with the vehicle-slab track coupled model including the comparison of two-and threedimensional models [16], the comparison of two-layered and three-layered slab tracks [17], the comparison of linear and nonlinear Hertzian contact theory [18], and the dynamic effects under different irregularities [19][20][21]. Furthermore, many efficient algorithms have been put forward to solve the nonlinear vehicle-track interaction problem [22][23][24][25].…”

“…Under the persistent loading-and-unloading process by vehicles, premature fatigue cracks are frequently observed in the rib-to-deck (RD) joints in OSDs after several decades of operation [4]. In some extreme cases in China, the deck could be poorly designed and fabricated, while the truck traffic can be heavy and of dynamic conditions [5,6]. Under this situation, fatigue cracks could even begin to initiate in the RD joints within only a few decades after construction [7,8].…”
