Modelling and predicting of the LCF-behaviour of aluminium auxetic structures

This study presents the experimental and computational analysis for determining the fatigue life of the auxetic cellular structures made of aluminium alloys. For the fatigue life calculation, the strain life approach was applied in the framework of the ANSYS software. The obtained experimental results were evaluated using the comprehensive statistical analysis, and presented in the form of different fatigue-life curves.Based on the reasonable agreement between computational and experimental results the proposed computational model was validated and can be used further for the fatigue studies of various auxetic structures made of Al-alloys.
