Nonlinear deformation analysis of CNTs with higher order Cauchy-Born rule based constitutive model

   Recently, we have developed a so-called higher order Cauchy-Born rule based
   constitutive model for the analysis of large deformation of CNTs [1]. It is
   a generalized quasi-continuum model for nano-structures.

   A computaional program is also developed based on the theoretical model
   presented in [1]. Some of the simulation results obtained with the developed
   program are summarized in the attached PDF file. From the computational results,
   it is shown that the higher order Cauchy-Born rule based model has the good
   capability to simulate the complex deformation of CNTs and graphene sheet.
