Evaluation of mechanical properties of linked zig-zag structure subjected to in-plane compressive load

Abstract

In this paper, the mechanical properties of two-dimensional zig-zag structure subjected to in-plane large compressive load was investigated. This structure has two counterphase layers consisted of inclined plate. The stiffness and the stored strain energy during the deformation were solved analytically based on the flexible bar theory proposed by Fly (1969). In particular, the effects of micro-architecture of the zig-zag model on these mecahnical properties were discussed. The obtained theoretical results agree fairly with FE results.
