| Abstract: | A Spline Finite Points Method (SFPM) of analysis elastic-plastic bending for beams and thin plates is firstly presented in the paper. Several numerical results are presented. From analyses, it is known that the SFPM is simpler, higher accuracy and more economy method in computing storage and time requirements than the Finite Element Method. It is easily carried out by a computer. This method is an effective method of numerical analysis on the special reqular region. Therefor, the SFPM is a mutual complement with the Finite Element Method. It will may be applied broadily by the engineers. |
