Verma, Amrit Shankar (author), Yan, Jiquan (author), Hu, Weifei (author), Jiang, Zhiyu (author), Shi, Wei (author), Teuwen, Julie J.E. (author)A fiber-reinforced composite wind turbine blade (WTB) is exposed to numerous impact threats during its service life causing damages that can be detrimental to its structural integrity. Currently, impact loads are not considered during blade design, so high safety factors are introduced, which result in a conservative design. However, as wind...review 2023

Shi, Can (author), Fan, Zheng (author), Connolly, David P. (author), Jing, Guoqing (author), Markine, V.L. (author), Guo, Y. (author)Railway ballast performance is dictated by a complex mix of mechanical properties. These effect its performance at the particle level for example in terms of particle degradation, but also at the track system level in terms of settlement and stability. Therefore this paper seeks to develop new understandings of ballast behaviour and identify...review 2023

Shi, Can (author), Zhou, Yu (author), Xu, Lei (author), Zhang, Xu (author), Guo, Y. (author)The dynamic performance of a railway track subjected to moving trains depends strongly on track support conditions. In reality, even for the well-constructed and well-maintained tracks, sleeper support stiffness and global track stiffness vary substantially along the track, which affects the train-track dynamic interactions, causing rapid...review 2023
