我们研究自然的非平坦的版本的所谓的“约束冯卡门”理论薄的非线性弹性薄膜。我们证明了单位圆盘上的每一个(容许的)径向对称离面位移是一个不动点。这使我们能够构建数据,导致约束冯卡门泛函有无穷多个固定点。
We study the natural non-flat version of the so-called "constrained von Karman" theory for thin nonlinearly elastic films. We prove that every (admissible) radially symmetric out-of-plane displacement on the unit disk is a stationary point. This allows us to construct data leading to constrained von Karman functionals which have infinitely many stationary points.
