Biological cellular materials are an important area of research in Additive manufacturing due to their intricate lightweight designs and forms with high energy absorption characteristics under compressive loading. In this study, we utilize the capability of Additive Manufacturing (AM) technology, experimental testing, and Finite Element Analysis (FEA) to design and investigate the mechanical behavior and energy absorption capabilities of novel Biomorphic Cellular Structures (BCS) inspired by the microstructure of cedar, oak, and palm wood. A comparative study of the elastic properties of the biomorphic cellular structures is carried out. The deformation and failure modes of the different cells were studied, and their performance was also discussed. Nonlinear finite element numerical simulation conducted has shown high accuracy in the prediction of deformation of the samples manufactured using additive manufacturing. The results show that cedar-bcs provides the best mechanical performance compared to the other two biomorphic cellular structures which could be as a result of its more vertical cell wall orientation, nevertheless, the palm-bcs showed a step-wise deformation and improved collapse stress. The obtained results suggest that the unique opportunities offered by the proposed experimental method, in combination with computational models, could serve to provide novel important information for the rational design of additively manufactured porous biomorphic materials.

生物细胞材料因其复杂的轻量化设计和在压缩载荷下具有高能量吸收特性的形式而成为增材制造的重要研究领域。在这项研究中，我们利用增材制造 (AM) 技术、实验测试和有限元分析 (FEA) 的能力来设计和研究受微结构启发的新型生物形态细胞结构 (BCS) 的机械行为和能量吸收能力。雪松、橡木和棕榈木。对生物形态细胞结构的弹性特性进行了比较研究。研究了不同电池的变形和破坏模式，并讨论了它们的性能。进行的非线性有限元数值模拟表明，使用增材制造制造的样品的变形预测具有很高的准确性。结果表明，与其他两种生物形态细胞结构相比，雪松-bcs 提供了最好的机械性能，这可能是由于其更垂直的细胞壁取向，然而，palm-bcs 表现出逐步变形和改善的坍塌应力. 获得的结果表明，所提出的实验方法提供的独特机会与计算模型相结合，可以为增材制造的多孔生物形态材料的合理设计提供新的重要信息。结果表明，与其他两种生物形态细胞结构相比，雪松-bcs 提供了最好的机械性能，这可能是由于其更垂直的细胞壁取向，然而，palm-bcs 表现出逐步变形和改善的坍塌应力. 获得的结果表明，所提出的实验方法提供的独特机会与计算模型相结合，可以为增材制造的多孔生物形态材料的合理设计提供新的重要信息。结果表明，与其他两种生物形态细胞结构相比，雪松-bcs 提供了最好的机械性能，这可能是由于其更垂直的细胞壁取向，然而，palm-bcs 表现出逐步变形和改善的坍塌应力. 获得的结果表明，所提出的实验方法提供的独特机会与计算模型相结合，可以为增材制造的多孔生物形态材料的合理设计提供新的重要信息。
