Self-propulsion of flapping bodies in viscous fluids: Recent advances and perspectives被引量：6
《Acta Mechanica Sinica》2016年第6期980-990,共11页Shizhao Wang Guowei He Xing Zhang 
supported by the Chinese Academy of Sciences (Grants KJCX-SW-L08, KJCX3-SYW-S01);the National Natural Science Foundation of China (Grants 11021262, 11023001, 11232011, 11372331)
Flapping-powered propulsion is used by many animals to locomote through air or water. Here we review recent experimental and numerical studies on self-propelled mechanical systems powered by a flapping motion. These s...

SIZE EFFECTS OF ELASTIC MODULUS OF FCC METALS BASED ON THE CAUCHY-BORN RULE AND NANOPLATE MODELS
《Acta Mechanica Solida Sinica》2014年第2期111-121,共11页Jianyun Liu Jingru Song Yueguang Wei 
Project supported by the National Natural Science Foundation of China(Nos.11021262,10932011 and 91216108);the National Basic Research Program of China(2012CB937500)
In the present research, a simple quasi-continuum model, the Cauchy-Born rule model, is used to investigate the size effects of elastic modulus for fcc metals. By considering a nanoplate model and calculating the stra...

JUMPING INSTABILITIES IN THE POST-BUCKLING OF A BEAM ON A PARTIAL NONLINEAR FOUNDATION
《Acta Mechanica Solida Sinica》2013年第5期500-513,共14页Yin Zhang Kevin D Murphy 
supported by the National Natural Science Foundation of China(Nos.11021262 and 11023001);Chinese Academy of Sciences(No.KJCX2-EW-L03)
Mode jumping is an instability phenomenon in the post-buckling region, which causes a sudden change in the equilibrium configuration and is thus harmful to structure. The con- figuration of a partial elastic foundatio...
