在力学中，识别与可处理的边值问题相对应的实验是有利的——这有助于数据简化和解释。然而，越来越多的情况出现，其中实验者无法在测试期间指定几何形状或应用的贷款。因此，逆有限元方法成为计算材料参数的重要工具。在本文中，我们提出的数值和实验结果表明，这样一种逆有限元方法对于表征轴对称和非轴对称有限膨胀下的新胡克（橡胶）膜的机械行为非常有用。
It is advantageous in mechanics to identify experiments that correspond to tractable boundary value problems - this facilitates data reduction and interpretation. Increasingly more situations are arising, however, wherein experimentalists cannot dictate the geometry or applied lends during testing. Inverse finite element methods are, therefore, becoming essential tools for calculating material parameters. In this paper, we present numerical and experimental results that show that one such inverse finite element method is very useful in characterizing the mechanical behavior of neo-Hookean (rubber) membranes subjected to axisymmetric and nonaxisymmetric finite inflations.
