Abstract


The control equation of the plane elastostatic problem under the scaled boundary coordinate system is derived by method of virtual work principle, and the solution of the governing equation is expounded. In a small example with a theoretical solution, we apply the proportional boundary finite element method to calculate and find that the accuracy of the result is very high.
