Finite Element Analysis on Out-of-Plane Compression Properties of Thermoplastic Honeycomb

Fan, Xinyu / Verpoest, Ignaas / Vandepitte, Dirk

Abstract In this paper, the out-of-plane compressive properties of thermoplastic hexagonal honeycombs are investigated by finite element analysis (FEA). Both linear (eigenvalue problem) and nonlinear buckling analyses are performed correspondingly on honeycomb perfect models and a hexagonal imperfect unit-cell model to determine actual honeycomb compressive properties. The numerical FEA results show much better agreement with the experimental results than other conventional theories.
