Honeycombs are widely used in engineering protection, while the gap between peak and mean stresses remains to be narrowed, interaction effects among walls weak. To break these limits, gradient curved‐walled honeycombs have been proposed recently. However, their in‐plane crashworthiness has never studied, which restricts actual applications complex load environment. For this purpose, article adopts experiments, finite‐element simulations, theoretical analysis reveal crash performance of honeycombs. Quasistatic dynamic experiments carried out for 3D‐printed honeycomb specimens made 316L stainless steel, numerical simulations conducted by ABAQUS/Explicit. Compared traditional straight‐ honeycombs, display stabler deformation mode more efficient mechanical response. Their EA SEA respectively 25.5% 6.4% larger than straight‐walled energy absorption force efficiencies nearly 2.4 5.3 times larger, respectively. On basis, plastic hinge model with high accuracy established, derive analytical solutions force–displacement relations. This work extends comprehensive properties application prospects sets an example develop effective simplification desirable on complex‐shaped structures.
