Abstract: The invention relates to a design method of high-temperature nickel-based bolts based on damage tolerance theory, comprising the following steps: S1: acquiring operating parameters for the design; S2: selecting a material for bolts; S3: acquiring mechanical properties of the materials; S4: determining a pretension stress σp of a single bolt; S5: determining the service stress σs under the steady state; S6: determining the number n, the effective cross-section area A and the distribution of bolts; S7: determining a maximum allowable crack dimension; S8: calculating the maximum allowable service stress σth using the crack propagation threshold Kth at the design temperature; S9: comparing the service stress σs and the maximum allowable service stress σth, if σs is smaller than σth, then the bolts are safe in the design life; otherwise, return to step S4 and reduce the pretension stress σp.
