Eight structural elements in biological materials are identified as the most common amongst a variety of animal taxa. These are proposed as a new paradigm in the field of biological materials science as they can serve as a toolbox for rationalizing the complex mechanical behavior of structural biological materials and for systematizing the development of bioinspired designs for structural applications. They are employed to improve the mechanical properties, namely strength, wear resistance, stiffness, flexibility, fracture toughness, and energy absorption of different biological materials for a variety of functions (e.g., body support, joint movement, impact protection, weight reduction). The structural elements identified are: fibrous, helical, gradient, layered, tubular, cellular, suture, and overlapping. For each of the structural design elements, critical design parameters are presented along with constitutive equations with a focus on mechanical properties. Additionally, example organisms from varying biological classes are presented for each case to display the wide variety of environments where each of these elements is present. Examples of current bioinspired materials are also introduced for each element.

生物材料中的结构设计元素：在生物启发中的应用

生物材料中的八种结构元素被确定为各种动物分类中最常见的元素。这些被提议作为生物材料科学领域的新范例，因为它们可以用作使结构生物材料的复杂机械行为合理化并使系统化用于结构应用的生物灵感设计系统化的工具箱。它们用于改善机械性能，即各种功能的各种生物材料（例如，身体支撑，关节运动，冲击保护，减轻重量）的强度，耐磨性，刚度，柔韧性，断裂韧性和能量吸收。确定的结构要素为：纤维状，螺旋状，梯度，分层，管状，蜂窝状，缝合线和重叠。对于每个结构设计元素，提出了关键设计参数以及本构方程，并着重于机械性能。另外，针对每种情况，提供了来自不同生物学类别的示例生物，以展示其中存在这些元素的环境的多样性。每个元素还介绍了当前受生物启发的材料的示例。
