本文考虑了由固定端点图给出的弹性曲线的障碍问题。我们给出了保证解存在的障碍条件,并讨论了它们的正则性。最后给出了一种数值方法来获得近似解。
We consider an obstacle problem for elastic curves given by graphs with fixed ends. We give conditions on the obstacles that assure existence of solutions and discuss their regularity. At the end we present a numerical method to obtain approximate solutions.
