A wide variety of deformation localization can be observed in solids and these mechanisms are related closely to the geometrical and mechanical properties of their microscopic structure. in this work, we derive the bifurcation problem of periodical square cells subjected to equi-biaxial compression, by using our developed flexibly jointed modeling. Then, displacement control and load control analyses are performed for multiple cell aggregates, and short wave-length and long wavelength buckling mechanisms including deformation localization are discussed from the standpoint of the collective joint-deformation with asymmetrical rotation mode.
