| 1 | DEVELOPMENT OF EXPERIMENTAL METHODS FOR IMPACT TESTING BY COMBINING HOPKINSON PRESSURE BAR WITH OTHER TECHNIQUES显示文摘The split Hopkinson pressure bar(SHPB) technique and the wave propagation inverse analysis(WPIA) technique are both extensively used to experimentally investigate the impact behavior of materials, although neither of them alone provides a fully satisfactory analysis. In the present paper, attention is given to new experimental techniques by incorporating a damagemodified constitutive model into the SHPB technique and combining the Hopkinson pressure bar(HPB) technique with WPIA. First, to distinguish the response due to dynamic constitutive behavior and the response due to dynamic damage evolution, the SHPB method incorporating a damage-modified constitutive model is developed, including an explicit damage-modified Zhu–Wang–Tang model and an implicit damage-modified constitutive model. Second, when the SHPB results become invalid, a method of combining new Lagrange inverse analyses with the HPB technique is developed, including cases of the HPB arranged in front of a long specimen and behind the specimen. As examples of these new methods, typical results are given for nonlinear viscoelastic polymers and concretes considering damage evolution, a super-elastic Ti–Ni alloy with phase transformation and an aluminum foam with shock waves propagating within it. | Lili Wang Shisheng Hu Liming Yang Zijian Sun Jue Zhu Huawei Lai Yuanyuan Ding | 2014 | Acta Mechanica Solida Sinica2014，27，4： | 9 |
| 2 | Modes of genetic adaptations underlying functional innovations in the rumen显示文摘The rumen is the hallmark organ of ruminants and hosts a diverse ecosystem of microorganisms that facilitates efficient digestion of plant fibers.We analyzed 897 transcriptomes from three Cetartiodactyla lineages:ruminants,camels and cetaceans,as well as data from ruminant comparative genomics and functional assays to explore the genetic basis of rumen functional innovations.We identified genes with relatively high expression in the rumen,of which many appeared to be recruited from other tissues.These genes show functional enrichment in ketone body metabolism,regulation of microbial community,and epithelium absorption,which are the most prominent biological processes involved in rumen innovations.Several modes of genetic change underlying rumen functional innovations were uncovered,including coding mutations,genes newly evolved,and changes of regulatory elements.We validated that the key ketogenesis rate-limiting gene(HMGCS2)with five ruminant-specific mutations was under positive selection and exhibits higher synthesis activity than those of other mammals.Two newly evolved genes(LYZ1 and DEFB1)are resistant to Gram-positive bacteria and thereby may regulate microbial community equilibrium.Furthermore,we confirmed that the changes of regulatory elements accounted for the majority of rumen gene recruitment.These results greatly improve our understanding of rumen evolution and organ evo-devo in general. | Xiangyu Pan Yudong Cai Zongjun Li Xianqing Chen Rasmus Heller Nini Wang Yu Wang Chen Zhao Yong Wang Han Xu Songhai Li Ming Li Cunyuan Li Shengwei Hu Hui Li Kun Wang Lei Chen Bin Wei Zhuqing Zheng Weiwei Fu Yue Yang Tingting Zhang Zhuoting Hou Yueyang Yan Xiaoyang Lv Wei Sun Xinyu Li Shisheng Huang Lixiang Liu Shengyong Mao Wenqing Liu Jinlian Hua Zhipeng Li Guojie Zhang Yulin Chen Xihong Wang Qiang Qiu Brian PDalrymple Wen Wang Yu Jiang | 2021 | Science China(Life Sciences)2021，64，1： | 3 |
| 3 | Microstructure characterization and thermal properties of the waste-styrene-butadiene-rubber (WSBR)-modified petroleum-based mesophase asphalt显示文摘In this work, waste-styrene-butadiene-rubber(WSBR)-modified petroleum-based mesophase asphalt was prepared through a co-carbonization process. The influence of contents of WSBR and carbonization temperature on the properties of mesophase asphalt was investigated. The chemical constituents,microstructure and thermal property of the samples were characterized. The results show that using WSBR as modifier can significantly promote the formation of mesophase. When the temperature is constant, the addition of WSBR results in more optically anisotropic crystal structure in the samples, and a better thermal stability. When the content of WSBR is invariable, with increasing temperature, the content of anisotropic structure in mesophase asphalt becomes higher and more uniform. The thermal stability of the samples is the best when WSBR content is 10 wt%. | Jingbo Hu Changqing Fang Shisheng Zhou Youliang Cheng Hanzhi Han | 2019 | Journal of Materials Science & Technology2019，35，5： | 2 |

| 8 | High Strain Rate Deformation Behavior of Zirconium at Elevated Temperatures显示文摘High temperature mechanical behaviors of zirconium at high strain rate of 103 s-1 were studied by split Hopkinson pressure bar (SHPB).The influences of strain rate and temperature on the micro-structural evolution,as well as the occurrence of shear localization and subsequent fracture,were also investigated.It s found that the compressive stress-strain response depends sensitively on the applied strain rate and test temperature.Micro-structural observations revealed that the density of the twinning grains reduced as the temperature increased,and increased in response to increasing strain rate.Optical observation of the fracture surfaces showed evidence of adiabatic shear localization along the fracture planes prior to crack formation.Finally,a special form of the Zerilli-Armstrong model was used to describe the mechanical response of zirconium. | Dawu Xiao Yinglei Li Shisheng Hu Lingcang Cai | 2010 | Journal of Materials Science & Technology2010，26，10： | 1 |

| 15 | Investigation of Heave Response of the Deepwater Octagonal FDPSO Using Various Heave Plate Configurations显示文摘Heave plates can be employed to control undesirable heave motion amplitudes of the deepwater octagonal Floating, Drilling, Production, Storage, and Offloading(FDPSO) platform. Numerical simulations and model tests were applied to analyze and investigate the hydrodynamic response and the feasibility of the heave plate configurations. The diameter and the depth below the free surface of a single-layer heave plate, as well as the spacing of two-layer heave plates, were considered as the primary variables when studying the effect of heave plates on FDPSO hydrodynamics. The analysis results indicate that the heave plate diameter significantly affects the heave hydrodynamics, and heave performance could be improved with an increased diameter. In addition, increasing the depth below the free surface of a single-layer heave plate does not effectively suppress the heave motion within the range of draft depths tested. The target FDPSO obtained better heave characteristics with increased spacing between the two-layer heave plates. Furthermore, the global performances of the octagonal FDPSO with these typical heave plate configurations were comparatively analyzed. The results indicate that from a hydrodynamic point of view, the single-layer heave plate configuration has an advantage over the two-layer heave plate configuration. | Chenfang Yu Zhiqiang Hu Shisheng Wang | 2017 | Journal of Marine Science and Application2017，16，4： | 0 |

| 20 | Amorphous calcium magnesium phosphate nanocomposites with superior osteogenic activity for bone regeneration显示文摘The seek of bioactive materials for promoting bone regeneration is a challenging and longterm task.Functionalization with inorganic metal ions or drug molecules is considered effective strategies to improve the bioactivity of various existing biomaterials.Herein,amorphous calcium magnesium phosphate(ACMP)nanoparticles and simvastatin(SIM)-loaded ACMP(ACMP/SIM)nanocomposites were developed via a simple co-precipitation strategy.The physiochemical property of ACMP/SIM was explored using transmission electron microscope(TEM),Fourier transform infrared spectroscopy(FTIR),powder X-ray diffraction(XRD)and highperformance liquid chromatograph(HPLC),and the role of Mg^(2+) in the formation of ACMP/SIM was revealed using X-ray absorption near-edge structure(XANES).After that,the transformation process of ACMP/SIM in simulated body fluid(SBF)was also tracked to simulate and explore the in vivo mineralization performance of materials.We find that ACMP/SIM releases ions of Ca^(2+),Mg^(2+)and PO_(4)^(3),when it is immersed in SBF at 37℃,and a phase transformation occurred during which the initially amorphous ACMP turns into self-assembled hydroxyapatite(HAP).Furthermore,ACMP/SIM displays high cytocompatibility and promotes the proliferation and osteogenic differentiation of MC3T3-E1 cells.For the in vivo studies,lamellar ACMP/SIM/Collagen scaffolds with aligned pore structures were prepared and used to repair a rat defect model in calvaria.ACMP/SIM/Collagen scaffolds show a positive effect in promoting the regeneration of calvaria defect after 12weeks.The bioactive ACMP/SIM nanocomposites are promising as bone repair materials.Considering the facile preparation process and superior in vitro/vivo bioactivity,the as-prepared ACMP/SIM would be a potential candidate for bone related biomedical applications. | Yingying Jiang Shuo Tan Jianping Hu Xin Chen Feng Chen Qianting Yao Zhi Zhou Xiansong Wang Zifei Zhou Yunshan Fan Junjian Liu Yize Lin Lijia Liu Shisheng He | 2021 | Regenerative Biomaterials2021，8，6： | 0 |
