Computational simulation of the relaxation of local stresses due to foreign object damage under cyclic loading
(2010)In this study, the phenomenon of residual stress relaxation from foreign object damage (FOD) is numerically simulated using a hybrid explicit¿implicit finite-element method. The effects of cycle fatigue loadings on stress ... -
Finite element modelling for mitigation of residual stress and distortion in macro-scale powder bed fusion components
(SAGE Publications, 2022-12-23)Powder bed fusion (PBF) has attracted significant attention in many applications due to its capability of fabricating complex and customized metal parts. However, the potential for high inherent residual stresses that ... -
Three-dimensional finite element modelling for additive manufacturing of Ti-6Al-4V components: Effect of scanning strategies on temperature history and residual stress
(Elsevier, 2022-03-22)A key challenge for metal additive manufacturing is the requirement to adapt process-structure-property methods currently under development to realistic, complex geometries. Of specific concern in the present work is the ...
