| 1 | BUCKLING AND POSTBUCKLING ANALYSIS OF ELASTO-PLASTIC FIBER METAL LAMINATES显示文摘The elasto-plastic buckling and postbuckling of fiber metal laminates(FML) are studied in this research. Considering the geometric nonlinearity of the structure and the elastoplastic deformation of the metal layers, the incremental Von Karman geometric relation of the FML with initial deflection is established. Moreover, an incremental elasto-plastic constitutive relation adopting the mixed hardening rule is introduced to depict the stress-strain relationship of the metal layers. Subsequently, the incremental nonlinear governing equations of the FML subjected to in-plane compressive loads are derived, and the whole problem is solved by the iterative method according to the finite difference method. In numerical examples, the effects of the initial deflection,the loading state, and the geometric parameters on the elasto-plastic buckling and postbuckling of FML are investigated, respectively. | Rengui Bi Yiming Fu Yanping Tian Chao Jiang | 2014 | Acta Mechanica Solida Sinica2014，27，1： | 2 |

| 3 | NONLINEAR DYNAMIC INSTABILITY OF DOUBLE-WALLED CARBON NANOTUBES UNDER PERIODIC EXCITATION显示文摘A multiple-elastic beam model based on Euler-Bernoulli-beam theory is presented to investigate the nonlinear dynamic instability of double-walled nanotubes.Taking the geometric nonlinearity of structure deformation,the effects of van der Waals forces as well as the non-coaxial curvature of each nested tube into account,the nonlinear parametric vibration governing equations are derived.Numerical results indicate that the double-walled nanotube(DWNT) can be considered as a single column when the van der Waals forces are suffciently strong.The stiffness of medium could substantially reduce the area of the nonlinear dynamic instability region,in particular,the geometric nonlinearity can be out of account when the stiffness is large enough.The area of the principal nonlinear instability region and its shifting distance aroused by the nonlinearity both decrease with the increment of the aspect ratio of the nanotubes. | Yiming Fu Rengui Bi Pu Zhang | 2009 | Acta Mechanica Solida Sinica2009，22，3： | 1 |
| 4 | Inorganic hollow mesoporous spheres-based delivery for antimicrobial agents显示文摘Microorganisms coexist with human beings and have formed a complex relationship with us.However,the abnormal spread of pathogens can cause infectious diseases thus demands antibacterial agents.Currently available antimicrobials,such as silver ions,antimicrobial peptides and antibiotics,have diverse concerns in chemical stability,biocompatibility,or triggering drug resistance.The“encapsulate-and-deliver”strategy can protect antimicrobials against decomposing,so to avoid large dose release induced resistance and achieve the controlled release.Considering loading capacity,engineering feasibility,and economic viability,inorganic hollow mesoporous spheres(iHMSs)represent one kind of promising and suitable candidates for real-life antimicrobial applications.Here we reviewed the recent research progress of iHMSs-based antimicrobial delivery.We summarized the synthesis of iHMSs and the drug loading method of various antimicrobials,and discussed the future applications.To prevent and mitigate the spread of an infective disease,multilateral coordination at the national level is required.Moreover,developing effective and practicable antimicrobials is the key to enhancing our capability to eliminate pathogenic microbes.We believe that our conclusion will be beneficial for researches on the antimicrobial delivery in both lab and mass production phases. | Yunping Qiao Yanyang Han Rengui Guan Shiliang Liu Xinling Bi Shanshan Liu Wei Cui Tao Zhang Tao He | 2023 | Frontiers of Materials Science2023，17，1： | 0 |
