| Abstract: | Based on the planar and spatial Kelvin's problem and Cauchy formula , this paper infers the basic displacement solution tensor Uij as well as surficial force tensor Tij, and then expresses the displacement formulas of elastic body in terms of boundary integration with Betti's principle . The formula is very useful for solving problems in solid mechanics . |
