| Abstract: | By using of the constitutive model developed by the higher-order Cauchy-Born rule and moving least square meshless method,buckling deformation for single walled carbon nanotube (7,7) is investigated in detail. The present results agree well with those of molecular dynamics method,which also present the deformation mechanism of (7,7) single walled carbon nanotube before and after buckling. |
