Empirical Investigation of Energy Absorption for 3D-Printed Auxetic Tubular Structures
Abstract
In light of the increasing imperative for sustainable and optimized design paradigms, 3D-printed structures have attained considerable prominence within engineering applications, particularly owing to their superior mechanical performance in energy absorption mechanisms. The objective of this investigation is to empirically characterize the fabricated cylindrical three-dimensional printed auxetic structures. The examined structure was produced utilizing fused deposition modeling (FDM) with polylactic acid (PLA) as the material. Following the empirical characterization of the energy absorption response of the structures subjected to quasi- static loading conditions, the critical parameters such as specific energy absorption (SEA) and crush force efficiency (CFE) were evaluated.
