Indenter size effect on the reversible incipient plasticity of Al(001) surface:Quasicontinuum study
《Chinese Physics B》2015年第8期501-507,共7页唐丹 邵宇飞 李久会 赵星 祁阳 
supported by the National Natural Science Foundation of China(Grant No.51172040);the National Basic Research Program of China(Grant No.2011CB606403);the General Project of Scientific Research from Liaoning Educational Committee,China(Grant No.L2014135)
Indenter size effect on the reversible incipient plasticity of Al(001) surface is studied by quasicontinuum simulations.Results show that the incipient plasticity under small indenter, the radius of which is less than...

GHOST FORCE INFLUENCE OF A QUASICONTINUUM METHOD IN TWO DIMENSION被引量：2
《Journal of Computational Mathematics》2012年第6期657-683,共27页Jingrun Chen Pingbing Ming 
The error caused by the ghost force is studied for a quasicontinuum method with planar interface in two dimension. For a special case, we derive an analytical expression of the error, which is exploited to prove that ...

Brittle-ductile behavior of a nanocrack in nanocrystalline Ni:A quasicontinuum study被引量：1
《Chinese Physics B》2012年第9期196-203,共8页邵宇飞 杨鑫 赵星 王绍青 
Project supported by the National Basic Research Program of China (Grant No. 2011CB606403)
The effects of stacking fault energy, unstable stacking fault energy, and unstable twinning fault energy on the fracture behavior of nanocrystalline Ni are studied via quasicontinuum simulations. Two semi-empirical po...

An Examination on Atomic-level Stress Calculations by Nanoindentation Simulation via the Quasicontinuum Method
《Journal of Materials Science & Technology》2010年第1期56-64,共9页Yufei Shao and Shaoqing Wang Shenyang National Laboratory for Materials Science, Institute of Metal Research, Chinese Academy of Sciences, Shenyang 110016, China 
supported by the National Basic Research Program of China (No.2006CB605103)
Nanoindentation simulations on single crystals AI and Cu via the quasicontinuum method have been performed. Two kinds of atomic-level local stress calculation methods, i.e. the coarse-grained local stress and the viri...

Quasicontinuum simulation of indentation on FCC metals
《中国有色金属学会会刊：英文版》2008年第5期1164-1171,共8页王华滔 秦昭栋 倪玉山 张文 
Project(10576010) supported by the National Natural Science Foundation of China and NSAF Foundation of China
Quasicontinuum simulations were performed to study the processes of incipient plastic deformation on three FCC metals (Ag,Ni and Pd) under the action of a rigid indenter.Four widths (9.3,18.6,27.9 and 37.2 ) of the in...

QUASICONTINUUM SIMULATION OF NANOINDENTATION OF NICKEL FILM
《Acta Mechanica Solida Sinica》2006年第4期283-288,共6页Zeng Fanlin Sun Yi 
A large-scale atom simulation of nanoindentation into a thin nickel film using the quasicontinuum method was performed. The initial stages of the plasticity deformation of nickel were studied. Several useful results w...
