| Abstract: | In this paper, we select the kelvin solution as the influence functio-nsca,lculate the influence function values at the real boundary for the finite point at the virtual domain with the collocation point method, in this domain the stress and displacement field can be obtained by superposing the influence function according to the principle of superposition. The example indicates that the accuracy of this method is high enough and the method is covenient. |
