Random heterogeneous microstructure construction of composites via fractal geometry
《Applied Mathematics and Mechanics(English Edition)》2019年第10期1413-1428,共16页Siwen WANG Zhansheng GUO 
Project supported by the National Natural Science Foundation of China(Nos.11972218 and11472165)
The microstructures of a composite determine its macroscopic properties. In this study, microstructures with particles of arbitrary shapes and sizes are constructed by using several developed fractal geometry algorith...

THREE DIMENSION QUASI-WILSON ELEMENT FOR FLAT HEXAHEDRON MESHES被引量：7
《Journal of Computational Mathematics》2004年第2期178-187,共10页Shao-chunChen Dong-yangShi Guo-biaoRen 
The well known Wilson's brick is only convergent for regular cuboid meshes. In this paper a quasi-Wilson element of three dimension is presented which is convergent for any hexahedron meshes. Meanwhile the element is ...
Hydrothermal Synthesis and Crystal Structure of [(CH_3CH_2)_4N]_4[(La_(12)(OH)_(12)MoO_(29) )], A Novel Cluster Compound with a MoO_5 Hexahedron Center Surrounded by La-O Octahedron
