...Long Yan; Weiya Xu; Rubin Wang; Qingxiang Meng Purpose The purpose of this paper is to investigate the anisotropic characteristics of the special structure of a columnar jointed rock masses and provide reference to forecast the behavioral characteristics of real samples. Design/methodology...

... an initial population of anisotropic materials based on FEM. The GA evolves the population of properties of anisotropic materials till a material is found whose mechanical response is the same as that of the nanocomposite. Findings The overall process is suitable for the constitutive relationships...
