An Energy-Based Approach for Fatigue Life Estimation of Welded Joints without Residual Stress through Thermal-Graphic Measurement
Mi, Chengji; Li, Wentai; Xiao, Xuewen; Berto, Filippo (Journal article; Peer reviewed, 2019)The traditional methodologies for fatigue life assessment of welded joints strongly depend on geometries and surface characteristics, as well as time. In this paper, an energy-based approach, independent of structures ... -
Lifetime assessment and optimization of a welded a-type frame in a mining truck considering uncertainties of material properties and structural geometry and load
Mi, Chengji; Li, Wentai; Xiao, Xuewen; Jian, Haigen; Gu, Zhengqi; Berto, Filippo (Peer reviewed; Journal article, 2019)In order to improve the fatigue performance of a welded A-type frame in a heavy off-road mining truck, a novel method was presented to implement lifetime and weight collaborative optimization while considering uncertainties ...
