Design and Characterization of 2.5D Nature-Inspired Infill Structures under Out-Plane Quasi-Static Loading Condition

The 2.5D (2.5-dimensional) structures are acquired to enhance safety and lightweight designs with better energy absorption in the aerospace automobile sectors. Additive manufacturing (AM), which is practical build suitable components industrial transportation applications, may produce these more efficiently. current study aims improve infilled mean crush force (MCF) capabilities. Under compression loading, proposed novel nature-inspired structure compared six existing geometries that inspired by nature. These made of cylindrical shells filled various infill configurations maintained at a consistent volume. Photopolymer resin used as material for structures, created using digital light processing (DLP) method under AM technology. characterization constructed models was done compressive out-plane quasi-static stress conditions. ANSYS numerical simulations have been carried out confirm dependability experimental data. impact supporting ribs on crushing behaviour thoroughly discussed. Mean specific (SEA) loading provided unique significantly boost qualities, axial collapse, behaviours.
