在本文中，三种类型的三重周期极小曲面（TPMS）被用来创建新的聚合物蜂窝材料（CM）。所考虑的TPMS架构是施瓦茨Primitive、Schoen IWP和Neovius。本工作研究这三个TPMS-CM的实验和计算的机械性能。3D打印用于制造这些聚合物多孔材料及其基础材料。测试它们的属性以提供输入并作为有限元建模的验证。两个有限变形的弹性/超弹性-粘塑性本构模型校准的基础上的基础材料的机械响应中使用的TPMS-CM的计算研究。结果表明，试样尺寸对TPMS-CM的力学性能有一定的影响。此外，有限元结果与实验结果一致。Neovius-CM和IWP-CM具有相似的力学响应，并且发现它们具有比Primitive-CM更高的刚度和强度。(C)2017爱思唯尔有限公司版权所有
In this paper, three types of triply periodic minimal surfaces (TPMS,) are utilized to create novel polymeric cellular materials (CM). The TPMS architectures considered are Schwarz Primitive, Schoen IWP, and Neovius. This work investigates experimentally and computationally mechanical properties of these three TPMS-CMs. 3D printing is used to fabricate these polymeric cellular materials and their base material. Their properties are tested to provide inputs and serve as validation for finite element modeling. Two finite deformation elastic/hyperelastic-viscoplastic constitutive models calibrated based on the mechanical response of the base material are used in the computational study of the TPMS-CMs. It is shown that the specimen size of the TPMS-CMs affect their mechanical properties. Moreover, the finite element results agree with the results obtained experimentally. The Neovius-CM and IWP-CM have a similar mechanical response, and it is found that they have higher stiffness and strength than the Primitive-CM. (C) 2017 Elsevier Ltd. All rights reserved.
