The use of metal-polymer membrane laminates for gossamer space structures emerge in recent times. Wrinkle formation, fold-line effect, and wrinkle minimization are more dominant in inflatable space structures and solar sail applications. In this article, the authors explored a novel work, wrinkle-crease interaction, for Aluminium-Kapton thin-film laminates. Introduction of non-avoidable crease profile adds uniqueness for laminates under in-plane shear deformation. A representative micro-material model from the experimental state of a layered membrane is employed in finite element analysis. This is followed by a non-linear post-buckling simulation performed for different layer combinations. The authors thoroughly investigated the layer composition and individual film thickness effect on the evolved wrinkling profile. Exploring wrinkle amplitude-wavelength for shear-induced compressive stresses in transverse direction confirms better results for creased laminate over a non-creased profile. In addition, a variation of shearing over changing film thickness support the stated remarks. This paper further suggests a favourable laminate thickness range to maintain the desired surface accuracy by limiting RMS error.

最近出现了将金属聚合物膜层压板用于游丝空间结构的情况。皱纹形成、折叠线效应和皱纹最小化在充气空间结构和太阳帆应用中更为重要。在这篇文章中，作者探索了一项新颖的工作，即 Aluminium-Kapton 薄膜层压板的皱纹-折痕相互作用。不可避免的折痕轮廓的引入增加了层压板在面内剪切变形下的独特性。在有限元分析中采用了来自分层膜的实验状态的代表性微材料模型。接下来是针对不同层组合执行的非线性后屈曲模拟。作者彻底研究了层组成和单个薄膜厚度对演变的皱纹轮廓的影响。探索横向剪切引起的压缩应力的皱纹振幅-波长证实了在无折痕轮廓上折痕层压板的更好结果。此外，随着薄膜厚度变化的剪切变化支持上述评论。本文进一步提出了一个有利的层压厚度范围，通过限制 RMS 误差来保持所需的表面精度。
