Recently, Vertical News, an American tech media, reported findings of the research group led by He Qingqiang, associate professor of college of mechanism and electronic engineering with the tile of “Findings from Q.Q. He and Co-Researchers Provides New Data on Finite Research”.
The paper，“Thermo-mechanical modeling and simulation of microstructure evolution in multi-pass H-shape rolling“ has been published by Finite Elements in Analysis and Design（Volume 76, 15 November 2013, Pages 13–20）. As the research stated, a set of mechanism-based constitutive equations was developed to model the effects of microstructure evolution on elastic–plastic flow of Q235 steel. This set of equations is implemented into the finite element (FE) solver ABAQUS for multi-pass shape rolling process simulation. The procedure for multi-pass rolling simulation was developed, a scheduled multi-pass rough rolling process of H-shape steel was carried out and the accuracy of the equations was validated by comparisons between the calculated mill load and measured ones. A numerical orthogonal experiment was designed to investigate the effects of rolling parameters on the microstructure evolution.
He Qingqiang has been working on finite elements theories and its engineering application for years and gained rich experience in these years.
