Low-cycle fatigue life methods for auxetic structures
Original language description
The objective of this paper is to introduce the fatigue life models (FLM) for auxetic (negative Poisson’s ratio) structures, in particular, low-cycle fatigue (LCF) life models. The mechanical properties of open and closed-cell foams can be described in first approximation by considering the density properties of the cellular solids. However, cell shape of foams could provide a significant contribution to the overall mechanical properties of the cellular solids. Auxetic structures are special version of cellular materials. Most of auxetic materials can be classified into three main groups: (i) auxetic honeycombs, (ii) auxetic microporous polymers and (iii) auxetic composites. There is no existed general fatigue life model for auxetic structures, therefore, different “mechanism” must be observed. The present study investigates the properties of existing LCF and its possibilities to be use for fatigue life calculation, considering the auxetic structures properties. Currently, first LCF experiments on potential auxetic materials are ongoing.
