Beams on elastic foundations – A review of railway applications and solutions

• Beam on elastic foundation theory is reviewed for railway engineering applications. Limitations of continuously supported models are explored. Multi-layer and discretely improve track dynamic response. Computationally efficient periodic semi-periodic solutions reviewed. Considerations given coupling tracks with vehicle subgrade models. widely employed when studying behaviour, applications such as dynamics, noise vibration. At a basic level, the use single continuous beam resting springs-in-series support straightforward to implement computationally efficient. However, it can also be extended simulate multi-layered nature tracks, which typically comprise variety components. Further, these coupled both Therefore, this paper presents state-of-the-art technical review theory, including exploration recent advancements in field. Firstly, modelling strategies solution methods computation behaviour These include approaches. extending approaches train-track interaction track-ground then provided. Finally, using aforementioned benchmark three common problem types given: noise, dynamics ground-borne
