INTRODUCTION Metals are the material of choice for many structural applications because
they provide the best compromise between strength and ductility. For applications in which …

Metallic materials experience irreversible deformation with increasing applied stress,
manifested in localized slip events that result in fatigue failure upon repeated cycling. We …

We have developed a micromechanical finite-element model of fatigue-crack initiation in
nominally defect-free pure fcc metals. The scale of observation envisioned is that of a single …

To examine the local conditions necessary to create cracks around cyclic slip bands, we
studied the evolution of surface topography by atomic force microscopy and deformation …

The fatigue life of a component can be expressed as the sum of two segments of life:(a) the
number of loading cycles required to initiate a crack and (b) the number of cycles it takes that …

Under stress, crystals irreversibly deform through complex dislocation processes that
intermittently change the microscopic material shape through isolated slip events. These …

This review paper providing a comprehensive review of insights gained from cyclic loading
discrete dislocation dynamics simulations and micro-scale fatigue experiments on …

In this article, the physical origin of fatigue crack initiation in ductile metals is discussed from
a historical perspective. The main focus is to assess those cyclic slip irreversibilities in a …

Abstract Analysis of inhomogeneous cyclic straining, observation of surface relief at
emerging persistent slip bands (PSBs) and data on point defect generation and migration in …

Current state and historical progress in experimental and theoretical studies of surface relief
appertaining to persistent slip bands (PSBs) and leading to fatigue crack initiation in …
