Special Issue Information

Disruptions in the operation of our countries’ infrastructure may put at risk the functioning of our societies and their economies. Such disruptions may result from many kinds of hazards and physical and/or cyber-attacks on installations and systems. Recent events demonstrate the increased interconnection among the impact of hazards, of the two kinds of attacks and, conversely, the usefulness for operators of combining cyber and physical security solutions to protect installations of the critical infrastructure globally. New ideas and innovation for comprehensive, yet installation-specific approaches are necessary to secure the integrity of existing or future, public or private, connected and interdependent assets, installations, and infrastructure systems.

This Special Issue ‘Extreme Sciences and Engineering’ enables transparent, fair, rapid communication of research that highlights the role of mechanics, sciences, and engineering in multidisciplinary areas across materials science, physics, and engineering. Emphasis is on the impact, depth, and originality of new concepts, methods, and observations at the forefront of applied sciences.

Among the topical areas of interest are:

  • Materials and components of extreme properties
  • Materials and structures under extreme conditions, such as high temperature and high loading rate, natural or man-made hazards, etc.
  • Resilience of assets, components, installations and infrastructure systems
  • Artificial Intelligence
  • Instability, large deformation, and large-amplitude vibration in nature and engineering systems
  • Interfacial phenomena in interactions between fluids and solids, deformation and failure of materials and structures
  • Self-assembly of materials, components, and structural systems
  • Mechanics of 3D printing
  • Earthquakes and tsunami
  • Digital built environments supporting crisis management, resilience recovery, and sustainability of critical infrastructures (airport, rail, port, energy, gas, etc.)
  • Advanced numerical methods for extreme conditions

Nowadays, timber sleepers are still used for ballasted railway tracks to carry passengers and transport goods. However, the process of natural decay causes the problem of timber sleeper degradation over time. A temporary “interspersed” approach is used to replace rotten timbers with concrete sleepers. This implementation has several inadequacies, as interspersed railway tracks have inconsistent stiffness and experience significant deterioration over the years. Increased heat due to the change in the global climate can induce a compression force in the continuous welded rail (CWR), leading to a change in track geometry called “track buckling”. A literature review shows that track buckling on plain tracks has been widely studied. However, the buckling of interspersed tracks has not been fully studied. This study presents 3D finite element modelling of interspersed railway tracks subjected to temperature change. The effect of the boundary conditions on the buckling shape is considered. The obtained results show that the interspersed approach may reduce the likelihood of track buckling. This study is the world’s first to investigate the buckling behaviour of interspersed railway tracks. The insight into interspersed railway tracks derived from this study will underpin the life cycle design, maintenance, and construction strategies related to the use of concrete sleepers as spot replacement sleepers in ageing railway track systems. The outcome of this study will help track engineers to improve the inspection of the lateral stiffness of interspersed tracks in areas prone to extreme temperature. Full article
