出于对非耗散材料建模的兴趣越来越大,本构关系比柯西弹性更一般,我们开始研究一类拉伸限制弹性弦:弦不能被压缩小于一定长度小于其自然长度,也不能被拉长大于一定长度大于其自然长度。特别是,我们考虑平衡状态下的重力(悬链线)的两点之间悬挂的字符串。我们研究的位置的支持导致拉伸状态包含可扩展和不可扩展的部分在两种情况下:退化的情况下,当字符串是垂直的和非退化的情况下,当支持是在相同的高度。然后,我们研究的存在性和多重性的平衡态一般与多重性显着不同的字符串满足经典的本构关系。
Motivated by the increased interest in modelling non-dissipative materials by constitutive relations more general than those from Cauchy elasticity, we initiate the study of a class ofstretch-limited elastic strings: the string cannot be compressed smaller than a certain length less than its natural length nor elongated larger than a certain length greater than its natural length. In particular, we consider equilibrium states for a string suspended between two points under the force of gravity (catenaries). We study the locations of the supports resulting in tensile states containing both extensible and inextensible segments in two situations: the degenerate case when the string is vertical and the non-degenerate case when the supports are at the same height. We then study the existence and multiplicity of equilibrium states in general with multiplicity differing markedly from strings satisfying classical constitutive relations.
