The normalized stress intensity factor (SIF) range of an inner-surface circumferential crack in a thin- tothick-walled finite-length cylinder under thermal striping was considered in this paper. The edges of the cylinderwere rotation-restrained and the outer surface was adiabatically insulated. Inner surface of the cylinder was heatedby a fluid with sinusoidal temperature fluctuation. An analytical temperature solution for the problem and our semianalyticalnumerical SIF evaluation method for the crack were combined, and as a result, it was shown that thetransient SIF solution can be expressed in a generalized form by dimensionless parameters such as mean radius towall thickness ratio, Biot number, normalized striping frequency and Fourier number. Finally, normalized SIFranges for the 1st cycle and steady state were given for these dimensionless parameters in tables for mean radius towall thickness ratio of 10, 5 and 1.
