A Quadratic $C^0$ Interior Penalty Method for the von K\'{a}rm\'{a}n Obstacle Problem
A quadratic C0 interior penalty method for the von Kármán obstacle problem is proved to have discrete solutions converging in the discrete energy norm with order O(h^α), where α is the biharmonic regularity index of the polygonal domain.
