相对论弹性力学中的静态球对称体

The static spherically symmetric body in relativistic elasticity

J. Frauendiener, A. Kabobel

摘要:

本文讨论了广义相对论弹性力学方程的一类静态球对称解。讨论的重点是比较两种物质模型的储能泛函,即,当系统变形时,给出系统中存储的能量的规则。这两种泛函模拟(和小变形近似)的经典基尔霍夫-圣维南材料,但不同的应变变量使用。我们讨论了大变形系统的行为。

英文摘要:

In this paper is discussed a class of static spherically symmetric solutions of the general relativistic elasticity equations. The main point of discussion is the comparison of two matter models given in terms of their stored energy functionals, i.e., the rule which gives the amount of energy stored in the system when it is deformed. Both functionals mimic (and for small deformations approximate) the classical Kirchhoff-St.Venant materials but differ in the strain variable used. We discuss the behavior of the systems for large deformations.
