由于变形行为的不确定性，机械超材料在工程应用中的应用往往受到限制。这种不确定性要求在包括超材料在内的机械设计中包含较大的安全系数和对其行为的假设，这有损于它们的最大利益，即。他们的超轻体重。在这项研究中，建立了弯曲为主和拉伸为主的蜂窝材料拓扑的屈服包络，以提高对蜂窝材料在不同载荷类型和方向下的响应的理解。实验研究表明，多孔材料的剪切强度明显低于摩尔准则的预测值，因此有必要对摩尔屈服准则进行修改。所有的拓扑在加载过程中都经历了拉伸-压缩各向异性和拓扑取向各向异性，其中以拉伸为主的拓扑经历了最大的各向异性。
The use of mechanical metamaterials in engineering applications is often limited because of uncertainty regarding their deformation behavior. This uncertainty necessitates large safety factors and assumptions about their behavior to be included in mechanical designs including metamaterials, which detracts from their greatest benefit, viz. their ultralight weight. In this study, a yield envelope was created for both a bending-dominated and a stretching-dominated cellular material topology to improve the understanding of the response of cellular materials under various load types and orientations. Experimental studies revealed that the shear strength of a cellular material is significantly lower than that predicted by Mohr’s criterion, necessitating a modification of the Mohr’s yield criterion for cellular materials. All topologies experienced tension–compression anisotropy and topology orientation anisotropy during loading, with the stretching-dominated topology experiencing the largest anisotropies.
