Examination of Vibration Response in Graded and Curved Auxetic Panels

Abstract

In this study, the effects of auxetic core patterns and boundary conditions on the natural frequencies of curved and graded auxetic panels were investigated. Numerical analyses were performed using ANSYS software under free-free (F–F) and clamped (C–C) boundary conditions to find the natural frequencies of flat and curved panels composed of tetrachiral, anti-tetrachiral, and hexachiral auxetic cells with constant bond length and node diameter. To validate the finite element results, vibration tests were conducted on flat auxetic panels under free boundary conditions. The simulation results show that the fundamental natural frequencies are significantly affected by the auxetic core pattern and boundary conditions. In particular, the hexachiral auxetic pattern has a greater effect on the natural frequency compared to anti-tetrachiral and tetrachiral cores. However, the effect of curvature on the natural frequency varies depending on the gradation and boundary conditions.
