J. Cent. South Univ. (2012) 19: 1796-1801 DOI: 10.1007/s11771-012-1210-3 First-principles investigation of cohesive energy and electronic structure in vanadium phosphides YANG Zhen-hua(杨振华)1... theory were employed to study the crystal structure of vanadium phosphide compounds, such as V3P, V2P, VP, VP2 and VP4. Cohesive energy of five types of vanadium phosphide compounds was calculated......
results, demonstrating that this method of determining the key parameters is likely accurate. The results also verify the correctness of the cohesive strength and fracture energy, the two key parameters...-reinforced structures. Key words: Al–Li alloy; cohesive zone model; adhesively bonded joints; fracture energy Cite this article as: YUAN Shun, LI Yi-bo, HUANG Ming-hui, LI Jian. Determination of key......

Cohesive strength and the critical strain energy for Mode-II interlamiar fracture of E-glass/epoxy woven fabrication were determined from... zone length as a material property was determined. To ensure the sufficient dissipation of energy, it was recommended that at least 4 elements should span cohesive zone length. Key words: cohesive zone......
, Changsha 410083, China) Abstract: A model was developed to account for the size, shape and structure dependent cohesive energy of metallic nanoparticles. The cohesive energies of V, Cr, Nb, Mo, Ta, W and Fe were calculated. The results show that the cohesive energy of nanoparticles of bcc structure is the same as that of fcc structure at the critical size and specific shape. When the nanoparticle......
