Jiaxuan Chi,Jiaxuan Chi,Zhongyi Cai,Zhandong Wan,Hongqiang Zhang,Zhenlin Chen,Liuhe Li,Ying Li,Peng Peng,Wei Guo +9 more
TL;DR: In this article, a post-treatment method combining heat treatment (HT) and laser shock peening (LSP) was employed to alter the microstructure and mechanical properties of WAAM Ti17 titanium alloy.
Journal ArticleDOI
Springback compensation method for doubly curved plate in multi-point forming
TL;DR: In this paper, an algorithm for springback compensation and modification for doubly curved plate was proposed by a combination method of theoretical analysis, numerical simulation and forming experiment, and the calculation equation for curvature was obtained based on an elastic-perfectly plastic biaxial bending model.
Journal ArticleDOI

Hepeng Zhang,Zhongyi Cai,Zhandong Wan,Peng Peng,Hongqiang Zhang,Rujian Sun,Zhigang Che,Chao Guo,Bo Li,Wei Guo +9 more
TL;DR: In this paper, the effects of laser shock peening on the microstructure, microhardness, residual stress, tensile and fatigue properties of 38CrSi steel were investigated.
Journal ArticleDOI
Multi-point forming of sandwich panels with egg-box-like cores and failure behaviors in forming process: Analytical models, numerical and experimental investigations
TL;DR: In this article, the authors investigated the mechanical feasibility to produce a doubly curved panel from an initially flat sandwich plate and found that the formability of sandwich panel with EBL cores in plastic forming process is mainly dominated by the failure modes of face sheet plastic wrinkling, face sheet plating dimpling and core cell fracture.
