Simultaneous enhancements of energy absorption and strength driven by hexagonal close-packed lattice structures of resin revealed by in-situ compression
A burgeoning interest pervades lattice structures' lightweight yet energy-absorbent traits. Nevertheless, the solitary damage mode of conventional lattice structures impedes augmented applications. Concretely, this work centered on engineering a novel structure (a hexagonal close-packed configuration inspired by biomimicry) to transform the compressive damage mode by altering lattice arrangements. Synchronously, the effect of compression rate and relative density variations on the mechanical properties and energy absorption of the lattice structures was also probed. Additionally, modifying lattice geometries to achieve altered compression failure modes enhanced mechanical performance. Notably, strength and energy absorption increased synergistically with escalating relative density and compression rate, exceeding the capabilities of classical lattice structures fabricated from conventional structures. The present work was expected to provide researchers and engineers with new insights into the design for both mechanical properties and energy absorption.
期刊介绍:
Thin-walled structures comprises an important and growing proportion of engineering construction with areas of application becoming increasingly diverse, ranging from aircraft, bridges, ships and oil rigs to storage vessels, industrial buildings and warehouses.
Many factors, including cost and weight economy, new materials and processes and the growth of powerful methods of analysis have contributed to this growth, and led to the need for a journal which concentrates specifically on structures in which problems arise due to the thinness of the walls. This field includes cold– formed sections, plate and shell structures, reinforced plastics structures and aluminium structures, and is of importance in many branches of engineering.
The primary criterion for consideration of papers in Thin–Walled Structures is that they must be concerned with thin–walled structures or the basic problems inherent in thin–walled structures. Provided this criterion is satisfied no restriction is placed on the type of construction, material or field of application. Papers on theory, experiment, design, etc., are published and it is expected that many papers will contain aspects of all three.
