Abstract: For no-smooth solution (u∈H或H),the authors define a new kind of error order by using projection type interpolation expansion,and then discuss the super-convergence and extrapolation of bilinear finite element with non-smooth solution.

Key words: non-smooth solution, bilinear element, extrapolation, super-convergence
