Abstract: Optimized and cost-effective railway track repair and maintenance planning requires periodic evaluation of railway track performance for which a track condition index is necessary. In particular, rail internal defects have ...

Abstract: Strength degradation of mass concrete of the Dez concrete arch dam was evaluated using inverse analysis methods. A three-dimensional nonlinear finite element model (FEM) was developed here for such an evaluation by considering ...

Abstract: This paper develops a new two-dimensional numerical model of vehicle/discontinuous slab track dynamic interaction. The vehicle is simulated as a multibody system with 10 degrees of freedom. The slab track is represented ...

Abstract: Passenger ride comfort (PRC) is one of the most important performance indicators of railway transportation. The current methods for computation and evaluation of railway ride comfort require measurement of train accelerations ...
