【Abstract】 In this paper is considered a semilinear elliptic variational inequality of fourth order with complementary boundary conditions. When the semilinear item is superlinearly increasing, the existence of the solutions is proved by applying critical point theory. The regularity is also obtaind with the aid of L~p-estimation.更多还原
