NUMERICAL SIMULATION AND PREDICTION OF AXIAL IMPACT LOAD FOR THIN-WALLED CIRCULAR TUBE WITH INTERNAL AND OUTER STAGGERED GROOVES by DU JinYu, YANG XiaoXiang, WEI TiePing, GUO JinQuan

“…The properties of energy absorption can be effectively improved by different induced structures for thin-walled straight tube.Finite element software（LS-DYNA） was used to simulate the transient response of thin-walled circular tube with internal and outer staggered grooves under axial impact.Axial shock characteristics of force for thin-walled circular tubes with different grooves were compared.The mean load formula considering strain rate effect was derived based on Hosseinipour ’s deformation model.Geometric parameter was introduced to predict peak load.The results show that the thin-walled circular tube with internal and outer staggered grooves can reduce 62.24% peak load and 56.26% mean load compared with thin-walled straight tube.The fold deformation is symmetrical and consistent with Hosseinipour’s deformation model.The prediction results of mean load and peak load are consistent with the finite element results.…”

Evidence for AGN Feedback in Galaxy Clusters and Groups by Myriam Gitti, Fabrizio Brighenti, Brian R. McNamara

“…Understanding the physics of the hot gas and its interplay with the relativistic plasma ejected by the AGN is key for understanding the growth and evolution of galaxies and their central black holes, the history of star formation, and the formation of large-scale structures. It has thus become clear that the feedback from the central black hole must be taken into account in any model of galaxy evolution. …”
