Numerical modeling of railway track supporting system using finite-infinite and thin layer elements

The present contribution deals with the numerical modeling of railway track-supporting systems-using coupled finite-infinite elements-to represent the near and distant field stress distribution, and also employing a thin layer interface element to account for the interfacial behavior between sleeper...
