The perforated auxetic tube with peanut-shaped perforations (PHT) are proposed and its mechanical responses investigated by three-point bending experiment validated finite element simulation. Compared to the elliptical (EHT) under same porosity, PHT exhibits significant improvement of up 100%, 49%, 34%, 148% in peak force, stiffness, ductility energy absorption capacity, respectively. Additionally, a parametric analysis is performed identify role each design parameter provide optimal solutions for design. This study provides valuable guidance enhancing properties tubes.

ABSTRACT In order to study the mechanical properties of glass panel structures applied automotive bridge decks, this paper conducted bending tests on decks under wheel loads. The experiment a concentrated load center plate, with displacement as control condition for loading. This process was repeated until all layers plates were completely destroyed. out‐of‐plane deflection field laminated plate lateral obtained using three‐dimensional Digital Image Correlation (DIC) method. results indicate that load–displacement relationship panels exhibits certain degree nonlinearity. Compared curve three‐layer structure, variation two‐layer structure is significantly closer linear. linear compared structure. direction maximum principal stress almost coincides diagonal and only shows significant fluctuations small load–stress nonlinear characteristics. By conducting experimental research subjected local loads, static response law multilayer pressure loads explored. can provide reference engineering practice.
