摘要

The mechanical behaviors of cissoidal hexagonal cores (CHCs) are investigated by using the finite element (FE) simulations under the in-plane quasi-static crushing loadings. The calculated deformation processes, response curves and values of plateau stress are presented in the forms of diagrams, force-displacement curves or data tables, respectively. The influences of ratio of cell wall thickness to edge length and expanding angle on the quasi-static plateau stress are discussed in detail. The empirical expressions of quasi-static plateau stress in terms of configuration parameters are given based on the FE simulation results.
