An energy-based fatigue life estimation and optimization of an electric mining dump truck welded frame

In consideration of uncertainties of material fatigue characteristics caused by the dimension size and manufacturing process, an interval strain energy density method for assessing fatigue life of welded structure was presented in this paper. Based on the limit experimental data, the data sequence w...
