TLDR
In this paper, a series of repeated impact tests for the in-situ prestressed concrete sleepers were carried out, ranging from a low drop height to the ultimate drop height where the ultimate failure occurred.About:

Composite railway sleepers – recent developments, challenges and future prospects
Wahid Ferdous,Allan Manalo,Gerard Van Erp,Thiru Aravinthan,Sakdirat Kaewunruen,Alexander Remennikov +5 more
TL;DR: In this paper, the authors rigorously review the recent developments on composite sleepers and identify the critical barriers to their widespread acceptance and applications and potential design approaches for overcoming the challenges in the utilisation and acceptance of composite sleeper technologies are also presented.

Experimental load rating of aged railway concrete sleepers
TL;DR: In this article, the structural evaluation program included quasi-static bending tests, dynamic impact tests, and tests to establish the current level of prestress in the steel wires using the dynamic relaxation technique.

Enhancement of Dynamic Damping in Eco-Friendly Railway Concrete Sleepers Using Waste-Tyre Crumb Rubber
TL;DR: It is recommended to consider the use of rubberised concrete (up to 10 wt. % crumb rubber) in designing railway sleepers as this will improve the service life of railway track systems and reduce wastes to the environment.

Cumulative damage in fatigue
TL;DR: The aircraft designer today is faced with the necessity of estimating not only the strength of a structure, but also its life — a task with which he was not confronted before.

Design of Concrete Structures
TL;DR: In this paper, the authors propose a yield analysis for edge-supported slabs and two-way column supported slabs, and a strip method for slabs in gradients.

Dynamics of Railway Bridges
TL;DR: In this paper, a model of railway bridges is proposed for the classification of random stress-time history, and the assessment of steel railway bridges for fatigue and thermal interaction of long-welded rail with railway bridges.
