Numerical evaluation on the deformation of REBCO pancake coil considering winding tension, thermal stress and screening-current-induced stress

The modulating effects of ascorbic acid (AA), vitamin E (E), and a combination of AA and E () against eight-hour road transportation stress were investigated in 120 pullets during the hot-dry season. The result obtained showed that handling, loading and transportation induced lymphopenia, neutrophilia, liveweight loss, and mortality, which was alleviated by oral administration of AA, E, and at doses of 60 mg, 30 mg, and mg per kg bodyweight, respectively, 30 minutes before being loaded and transported. The meteorological conditions recorded during the study period were higher () than the thermoneutral values established for chickens in the zone. In conclusion, the administration of vitamins AA, E, and , especially AA, ameliorated the risk of adverse effects of handling, loading, transportation, and thermal stress in pullets during the hot-dry season.

This paper presents a finite element based multi-scale model for a lithium-ion (Li-ion) battery cell. The model considers multi-physics including battery kinetics, diffusion, thermal and stress analysis. In battery thermal analysis, the heat source is critical. In this model, both resistive and entropic heating were considered. Simulations were carried out for a LiC6/LiPF6/LiyMn2O4 cell under a discharge-charge cycle. The heat generations due to these two heat sources were compared. The thermal stress was computed and compared with the intercalation stress for individual battery components. Within the electrode particles, the thermal induced stress was negligible. In the separator, however, the thermal induced stress was comparable or even higher than the stress caused by intercalation deformation of the electrode particles.
