Journal ArticleDOI
A new approach to correlate the defect population with the fatigue life of selective laser melted Ti-6Al-4V alloy
Yanan Hu,Shengchuan Wu,Shengchuan Wu,Zhengkai Wu,X.L. Zhong,Saad Ahmed,S. Karabal,Xianghui Xiao,Hui-Lan Zhang,Philip J. Withers +9 more
TL;DR: In this article, the defect-tolerant design of SLM Ti-6Al-4V alloy was evaluated in terms of the defect population using a combination of the statistics of extremes and the Murakami model.
Journal ArticleDOI
In situ X-ray imaging of fatigue crack growth from multiple defects in additively manufactured AlSi10Mg alloy
Weijian Qian,Shengchuan Wu,Shengchuan Wu,Zhengkai Wu,Saad Ahmed,Wen Zhang,Guian Qian,Philip J. Withers +7 more
TL;DR: In this paper, a synergistic multiple fatigue crack growth (smFCG) model was developed based on multiple defects measured a priori by X-ray CT to depict the competitive cracking effect.
Journal ArticleDOI
Hot dwell-fatigue behaviour of additively manufactured AlSi10Mg alloy: Relaxation, cyclic softening and fracture mechanisms
Jianguang Bao,Jianguang Bao,Zhengkai Wu,Shengchuan Wu,Philip J. Withers,Fei Li,Saad Ahmed,Adil Benaarbia,Wei Sun +8 more
TL;DR: In this paper, the results of high temperature strain-range controlled low cycle fatigue tests of a laser powder bead fused AlSi10Mg alloy were presented, and the bulk mechanical responses were found to exhibit a continuous cyclic softening, decreasing stress relaxation and decreased energy dissipated per cycle.
