Introduction Creep and stress relaxation are the inherent mechanical behaviors of stainless steel bolting materials at elevated temperature in a power plant.
The relationship between the residual stress and time during stress relaxation has been derived from the creep equations to analyze the stress relaxation curves of various different materials.
(1) where A, σ0, n, α, β are material parameters, is the creep strain rate, and σ is stress.

According to the expression of Euler critical load in mechanics of materials: (5) Where is the length factor; is the Young’s modulus;is the effective length of the beam and is the inertial moment .We can get the critical load of the structure is 46.62，and according to the expression of axial stress: (6) We know the maximum stress force is 68.6, which is less than the allowable stress of the material which is 200.
Young’s modulus and the density of the material are and respectively, and Poisson ration is 0.29. 3.1 Analysis of Single Beam FEM model of the resonant beam is shown in Fig.2.
