| beschreibung | For the long-term exposure to temperature load, certain parts of a concrete structure have more or less cracks during their construction or operation period. Obviously, the existence of cracks disrupts the heat transmission, having a significant impact on the existed cracks, and is not conducive to operate the structure safely. Thus, it is necessary to calculate and analyze the temperature field. XFEM was introduced into the analysis of the temperature field in hydraulic structures for its unique advantage of solving discontinuous problems, in this paper. Firstly, the approximation form of the temperature field of cracked structure was analyzed and provided; and then the discrete equations for solving discontinuous temperature field was deduced, where the crack was simulated by isothermal form, namely, the temperature field is continuous but its first derivative is not continuous; and then the temperature field by XFEM was established. A numerical example of a cross shaped plate... |
