Thus, through this research work, a novel computational framework is designed to assess real-time dynamic responses of surface stress raisers. Analytical outcomes generated through the stress intensity analysis and fatigue life evaluations have clearly confirmed the application of the developed design framework as a sustainable strategy for achieving reliable bearing capacity of dynamically loaded systems. © 2021 The Authors.

Introduction Surface flaws formed by manufacturing process or loading are almost inevitable and often difficult to detect in time, posing a threat to safety and durability of large moving systems. Thus, the development of a computational framework, which provides the required support during the design and in-service operations, is highly significant. The implementation of sustainable strategies driven by high performance failure assessments and budget saving is a demanding issue that continuously attracts the attention of researchers. Through the fatigue analysis, Guo (1993) introduced analytical solutions to generate the driving mode of quarter-elliptical damage at a hole subjected to biaxial and pin loadings. Kim et al. (2003) demonstrated that the crack growth law proposed by Forman (1972) coupled with the effective stress intensity factor and the weight function method can be used to analyze a pin-loaded Abstract Modern trends in failure prevention of large moving systems require understanding of surface flaw phenomena caused by complex loa .
