Abstract : A theoretical solution is derived for determining the state of stress of a long solid cylinder with a star-shaped central cavity having an arbitrary number of rays. The stresses are caused by a plane stationary temperature field and by a uniformly distributed pressure on the internal and external surfaces. The cylinder material is assumed to be homogeneous and its mechanical characteristics only insignificantly dependent on temperature. Under these assumptions, a solution to the problem is obtained by the N. I. Muskhelishvili method using functions of a complex variable, and formulas are derived for calculating the final total stresses on the inner and outer surfaces of the cylinder.
