Special Issue Information

Dear Colleagues,

Many properly designed and constructed bridge structures are damaged during their operation. Cracks are particularly dangerous, mainly due to their sudden and uncontrolled development, and lead to failures in many situations. Concerning metallic bridges, damage to their individual parts and whole structures, as well as a significant reduction of the strength of the material from which historic buildings are made, may result in a reduction of the load-carrying capacity. In such situations, there is a reasonable suspicion that the current load capacity may not be sufficient for the safe use of these facilities.

This imposes a natural requirement for continuous monitoring of the metallic bridges, as well as verification of their current load-carrying capacity. In the case of damaged structures, this requires the use of advanced methods, based mainly on fracture mechanics and damage mechanics. The application of methods based on damage mechanics has great potential, due to the possibility of modeling the material failure initiated at the microstructure. At the later stage of the material deformation, it enables determining the decrease in material strength and predicting its decohesion. Thanks to that mechanics-based methods are used in the assessment of engineering structures, among others. In the case of bridges, it is possible to model the time of the failure of their parts, and consequently, to determine the current load-carrying capacity of the entire structures.

This Special Issue covers new developments in the field of damage mechanics of materials and structures in bridge engineering. Topics include theoretical and practical studies focused on the damage mechanics-based assessment of parts, members, and whole structures of metallic bridges. Original research papers, reviews, and short communications reporting the results of experimental, theoretical, and/or computational work on any aspect of research in the subject scope are welcome. We look forward to your contributions.

This review paper discusses the basic problems related to the use of cohesive models to simulate the initiation and development of failure in various types of engineering issues. The most commonly used cohesive zone models (CZMs) are described. Recent achievements in the field of cohesive modeling are characterized, with particular emphasis on the problem of mixed mode loading, the influence of the strain rate, the stress state triaxiality, and fatigue. A separate chapter of the work is devoted to the identification of cohesive parameters. Examples of the use of CZMs for the analysis of the fracture and failure process in various applications, both on the macro and microscopic scale, are given. The directions of CZMs development were indicated as well as the issues that are currently under particularly intensive development. Full article
