摘要: Auxetic honeycombs exhibit low weight, shear stiffness, and excellent energy absorption capacity and thus have great potential for achieving the requirements of crashworthiness and lightweight in automotive fields. This work presents a novel auxetic structure called the star-triangular honeycomb (STH), in which the horizontal and vertical ligaments of the star honeycombs (SH) are replaced with triangular structures. The dynamic crushing behaviors of the STH under three different crushing velocities were investigated using 1D shock theory …
