Abstract: The paper investigates the causes of high-rate rail/weld failure on a heavy haul track using real life rail weld fracture data. The results show that despite the significant progress in rail manufacturing, and rail welding ...

Abstract: The allowable bending fatigue stress in a rail will determine the maximum allowable speed, which is then checked against the current operating speed. Therefore, some sensible value of allowable bending fatigue stress must ...

Abstract: This paper investigates the status of lateral stability of a ballasted curved track, which is carried out under four loading scenarios in terms of the factor of safety against displacement as the indicator. Then, the ...

Abstract: Pipelines are primarily instrumental for the transportation and distribution of bulk products from one part of a country to another as well as removing finished products from refineries to terminals and depots. Petroleum ...

Abstract: In an earlier paper, allowable bending fatigue stress was expressed in terms of ultimate tensile strength. For many reasons, it is useful to express allowable bending fatigue stress in terms of hardness. Hardness is ...

Abstract: Pipelines are primarily instrumental for the transportation and distribution of bulk products from one part of a country to another as well as removing finished products from refineries to terminals and depots. Petroleum ...

Abstract: Three ground‐water management models were developed to determine the optimal planning and operating policies of a multiaquifer system in eastern Saudi Arabia for an eight‐year planning period. The modeled system, which ...

Abstract: Full equilibrium superelevations are rarely installed on tracks. Consequently, trains run on unbalanced superelevations. Currently, the maximum curving speed is modeled with blanket unbalanced superelevations. Blanket ...

Abstract: In the literature, the length of a clothoid spiral usually is determined by three equations. These equations do not lead to the same length. As a result, all equations are applied and the maximum length is chosen. Of these ...
