Abstract:
ABSTRACT Cold expansion is the most effective technique to improve the strength and fatigue life of engineering components with fastener holes. Cold expansion creates a compressive residual stress field around the fastener hole, consequently reduces the tensile stress field under remotely applied loads and delays the fatigue crack initiations and propagation. The residual stress field plays an essential role in fatigue life of such specimens. Therefore, it is of great importance to have an accurate estimation on residual stress magnitude and distribution. This paper employs the non-ordinary state-based peridynamics to predict the residual stresses distribution in a cold expanded fastener hole. The obtained results are validated through comparison with available experimental and finite element results. The presented modeling method provides a promising technique in modeling cold expansion and effectively can be applied to predict the fracture behavior of cold expanded fastener holes under static and cyclic loading. Keywords: Cold expansion; Fastener hole; Peridynamics; Residual stress.
