Abstract

Modeling for fatigue of honeycombs under in-plane multiaxial loads is proposed and presented here. Paris law for microcrack propagation, Basquin law for high cycle fatigue and Coffin-Manson law for low cycle fatigue are employed to describe the fatigue of solid cell walls within honeycombs, respectively. As a result, the number of cycles to failure of honeycombs can be obtained by using a cell-wall-bending model and dimensional argument analysis. It is found that the fatigue of honeycombs under in-plane multiaxial loads depend on cyclic stress range, pre-existing macrocrack and microcrack lengths, cell size, relative density and the fatigue parameters of solid cell wall material.
