Stress configuration‐based classification of current research on fatigue of reinforced and prestressed concrete

Abstract

The limited understanding of the fatigue behavior of reinforced and prestressed concrete members is one of the reasons why many structures do not reach their expected service life. Without a deeper theoretical understanding of the fatigue phenomena in the various fatigue process zones, reliable fatigue life predictions are not possible. This paper provides a classification of the major fatigue process zones and mechanisms in reinforced and prestressed concrete members, accompanied by a brief review of recent developments in design rules, experimental characterization, and modeling approaches specific to each fatigue process zone and mechanism. The limitations of current approaches to fatigue characterization and modeling are also discussed, highlighting the need for further research in this area.

Phase-Field Modeling of Fatigue Crack Propagation in Brittle Materials

“…However, it is important to recognize that these models tend to represent fatigue crack growth as a one-dimensional mechanism. As a result, their applicability in capturing realistic fatigue-induced degradation is limited for more general loading configurations, such as mode II and mixed mode fracture conditions [25,26].…”
