| 1 | Computational explosion mechanics and related progress显示文摘Explosion mechanics is the theoretical basis for the design of highly efficient arms and ammunition and industrial explosion safety. Because it involves the complex physical and mechanical behaviors of multi-materials under extreme conditions, such as high speed, high temperature and high pressure, it is almost impossible to give exact solutions | YANG GuiTong | 2011 | Chinese Science Bulletin2011，56，33： | 3 |
| 2 | The Anomalous Response of Elastoplatic Circular Plates Under Impulsive Loading显示文摘The anomalous nonlinear elastic, perfectly plastic response behaviors of circular plate subjected to short transverse pulse load is studied. The plate is assumed fixed-pin along the boundary. 'Anomalous' here means that the final deflection may be in the direction opposite that of the load. It has been found by detailed numerical analyses that there exists anomalous response in some narrow loading ranges, so called slots. By further calculations it is shown that this special dynamic behavior is related to coupling affects of internal forces and large plastic deformation after removal loading. Further plastic dissipation will be lead to anomalous dynamic response. This phenomena could be considered as the coupling of the geometry nonlinearity, material nonlinearity,elastic effects and the irrecoverable of the plastic deformation. | Wu guiying Liu wei Yang guitong | 2004 | 上海交通大学学报2004，38，z2： | 3 |
| 3 | THE GLOBAL DEFORMATION AND LOCAL DAMAGE ANALYSIS OF FILLED METALLIC CYLINDRICAL SHELLS IMPACTED BY MISSILES显示文摘A group of theoretical models has been developed for analyzing transient dynamic re-sponse to filled metallic cylindrical shells impacted by flat-nosed missiles at normal obliquity on the ba-sis of the analogy modeling method of beam-on foundation.It can be used for solving the global defor-mation and the local failure of cylindrical shells in the impact process.The ballistic limit speed and im-pact response history have been calculated by this group of theoretical models,and the inner pressureeffect on the ballistic limit speed and some parameters are discussed at length.The quantitative rela-tionship between internal pressure and the ballistic limit speed and some significant conclusions havebeen obtained,which are basically identical with previous experimental results. | Li Zhu Zhang Shanyuan Yang Guitong | 1999 | Acta Mechanica Solida Sinica1999，12，3： | 2 |

| 19 | Comparison of biochar properties from 5 kinds of halophyte produced by slow pyrolysis at 500℃显示文摘Glycophyte biomass-derived biochars are currently concerned in most studies.However,little attention is given to the char-acteristics of halophyte-derived biochars.In this study,five typical halophytes of euhalophytes(Suaeda altissima,Suaeda salsa,and Kalidium foliatum),recretohalophytes(Phragmites australis),and pseudohalophytes(Tamarix chinensis)which are widely distributed in the arid and semiarid regions of northwestern China were selected for producing biochars with a slow pyrolysis process at 500℃for 1 h.The harvested biochars were characterized in elemental content,pores,surface area,and surface charges,and then their potential value as a soil conditioner was evaluated.The results showed that the halophyte-derived biochars had variable ash and Na+contents,ranging from 7.26 to 23.64%and 1.06 to 33.93 g kg^(−1)respectively.The EC value of the biochars ranged from 1.76 to 23.45 mS cm^(−1).The biochar derived from Suaeda altissima had a very low specific surface area(SSA),3.50 m^(2)g^(−1),while that derived from Phragmites australis(BPA)had a very high SSA,344.02 m^(2)g^(−1).All the biochars carried both positive and negative charges.Kalidium foliatum biochar(BKF)possessed more nega-tive charges,while Suaeda altissima biochar(BSA)contained more positive charges.In general,the halophyte biochars had a higher ash content and lower point of zero net charge(PZNC)value,compared with the biochars derived from glycophytes,which would imply their higher potential value as an acidic soil conditioner. | Hongyang Xiao Qimei Lin Guitong Li Xiaorong Zhao Jianzhong Li Erzhen Li | 2022 | Biochar2022，4，1： | 0 |
| 20 | A New Simple Model for the Mushrooming Deformation of Projectile Impacting on A Deformable Target显示文摘Based on Taylor's model and Hawkyard's model, a new simple model for the mushrooming deformation of projectile impacting on a deformable target is installed considering the penetration of the projectile to the deformable target. In the model, the following time-dependent variables are involved in: the extent and the particle velocity in the rigid zone; the extent, the cross-section area and the particle velocity in plastic zone; the velocity and depth of the penetrating of projectile to the target. Solving the set of equations, analytic solution is given. The profiles of deformed projectile and shape parameters for different initial impact velocities are shown. The duration time of deformation increases with increasing the impact velocity. The analytical results by using this model are coincident with experimental result. | Zhang Xiaoqing Yang Guitong | 2004 | 上海交通大学学报2004，38，z2： | 0 |
