Abstract
Bio-inspired structures have been commonly used in robotics, aerospace, and bioengineering because of their extraordinary qualities. The present study investigates compressive behavior for bioinspired cores. The experimental compression behavior of the bioinspired cores is supported with numerical analysis. As bioinspired structures are complex in nature, it is difficult to fabricate with the conventional technique. powder bed fusion (PBF) is employed to overcome this difficulty. Further specific energy absorption due to the compression behavior of the bioinspired cores and residual stress induced during the manufacturing process is investigated in detail, and the best-performing bioinspired core is reported in this study.
