A preliminary study ofnumerical manifold method in P-adaptive analysis

 Numerical manifold method was applied to P-adaptive analysis in this paper. First,displacement function with different order polynomials on the element was presented,the element matrices were given thereby. Meanwhile,Goodman element was introduced and the corresponding element matrices were also offered. Then a computer program for the P-adative analysis was coded. Numerical examples show the correctness of the algorithm.
