| Abstract: | The problem of the thermal deformation of the ring with difference elastic modulus in tension and compression is studied.The elasticity center method of structure mechanics is used to obtain the canonical equation of thermal deformation of the ring with difference elastic modulus in tension and compression under the temperature action.Then,the bending moment expression and the axial force expression are got.By the analysis of an example,the influence of temperature change on the ring section of the bending moment and axial force are discussed. |
