Mechanical response of a novel hybrid tube composed of an auxetic outer layer

In this study, the deformation and energy absorption characteristics of a novel hybrid tube is investigated both experimentally numerically. The architecture proposed composed an inner conventional co-axially arranged outer auxetic tube. Quasi-static compressive tests were conducted on tubes, tubes tubes. A three-dimensional digital image correlation technique was used to monitor evolution radial contraction Measured performance compared in terms force, absorption, specific absorption. Finite element (FE) models also developed for three types analyzed using ANSYS/LS-DYNA, validated by experimental measurements. Both numerical results showed that presence alters mode exerting force. Parametric studies performed investigate effects tube, wall thickness failure strain, yield strength tube’s material mechanical Increasing improved significantly.
