...Kunjie Sun; Chen Sun; Jubing Chen Stoney formula is widely used in advanced devices to estimate the residual stress of thin film/substrate system by measuring surface curvature. Many hypotheses including that thin film thickness is ignored are required, thus bringing significant error...

.... Three distinct buckling analyses are carried out: (1) elastic buckling accounting only for the geometry of the dent, (2) elastic buckling accounting for both dent geometry and residual stresses, and (3) a full elastic–plastic buckling analysis accounting for both the dent geometry and residual stresses...

...Lingxiao Yuan; Weike Yuan; Gangfeng Wang Residual stress can strongly affect the mechanical behaviors of engineering components. In this work, the authors revisit the role of equi-biaxial residual stress in the spherical indentation of elastoplastic solids by the finite element method. When...

...Xu Song; Alexander M. Korsunsky The aim of the present study was to introduce a new algorithm for reconstructing the eigenstrain fields in engineering components. A 2D discrete inverse eigenstrain study of residual stresses was carried out on a worn railhead sample. Its residual elastic strain...

...Andi M. Limarga; Robert Vaßen; David R. Clarke The residual stress distribution in plasma-sprayed zirconia thermal barrier coatings subjected to cyclic thermal gradient testing was evaluated using Raman piezospectroscopy and finite element computation. The thermal gradient testing (approximately...

... dependency of the material behavior and the complex description of the plastic flow near stress-free voids. Both bounds (“dual bounds”) are adjusted to capture Gurson-like porous materials with noninteractive voids. General residual stresses (either real or virtual) are presented in the analysis...

... stress amplitudes (or equivalently, exhibiting a prolonged fatigue life) before disruption by ratcheting . Various fatigue experiments which were found in the open literature, are in a satisfactory agreement with the theoretical analysis. The notion that the compressive component of residual stress can...
