摘要

In this paper, we model three different yielding mechanisms of hexagonal honeycombs with nonuniform cell-edge thickness under in-plane biaxial loads to develop equations describing their yield surfaces. The nonuniform cell-edge thickness of hexagonal honeycombs is taken into account in determining the locations of plastic hinges and corresponding yield surfaces. Results indicate that the yield surfaces for hexagonal honeycombs with nonuniform cell-edge thickness depend on their relative density and the distribution of solid between three cell edges and a vertex. The effects of solid distribution on the yield surfaces, hydrostatic and deviatoric yield strengths of hexagonal honeycombs under in-plane biaxial loads are also investigated.
