Resum:Existing refined creep calculation methods primarily include the numerical recursive method. Previous algorithms merely provided a theoretical possibility for refined creep calculations. Their massive computational load, complex derivation processes, and limited applicability conditions made it difficult to apply them practically in engineering. Therefore, this study improves upon existing refined creep algorithms by proposing two new calculation methods: the trapezoidal method and the difference method. The study shows that when calculating creep under different conditions, the proposed methods only require adjustments to certain elements in the calculation model, without the need to re-derive the creep calculation formula; this thus provides a convenient solution for creep calculation under varying operating conditions. Compared to the traditional numerical recursive method, the proposed methods significantly reduce computational effort; compared to the midpoint integration method, the proposed methods offer broader applicability. Under different calculation conditions, both methods exhibit high computational accuracy.
