摘要

在这项工作中，我们使用有限元DKT18，用渐近数值方法(ANM)数值研究了倾斜膜上皱纹的消失。ANM是一种路径跟踪技术，已被用于解决分支问题。我们用数值方法证明了Föppl-von Kármán (FvK)理论中膜位移梯度对应的项对拉伸弹性膜的分岔曲线的影响。我们还将使用ANM算法，数值研究厚度和纵横比对矩形弹性膜在拉伸过程中的再稳定的影响。并与工业代码ABAQUS的计算结果进行了比较。

ANM analysis of a wrinkled elastic thin membrane

In this work, we have investigated numerically the disappearance of wrinkles from a tended membrane by the Asymptotic Numerical Method (ANM) using the finite-element DKT18. The ANM is a path-following technique that has been used to solve bifurcation problems. We show numerically the influence of the terms corresponding to the membrane displacement gradient in the Föppl–von Kármán (FvK) theory on the bifurcation curves in the case of a stretched elastic membrane. We will also study numerically, by using the ANM algorithm, the influence of the thickness and of the aspect ratio on the re-stabilization of a rectangular elastic membrane during stretching. The results obtained by our model are compared with those obtained using the industrial code ABAQUS.
