stress and high initial residual stress is expected to cause the residual stresses relaxation. Only a few papers seem to deal with appropriate procedures for fatigue analysis and crack growth... elastic-plastic finite element analysis. The effect of residual stress relaxation, initial residual stress, and the applied load after variable amplitude cyclic loading is revealed, and a formula......

J. Cent. South Univ. (2019) 26: 728-742 DOI: https://doi.org/10.1007/s11771-019-4043-5 Dynamic stress accumulation model of granite residual soil under cyclic loading based on small-size creep......
Influence of Residual Stress on the Dimensional Instability of 7075 Aluminum Cone-Shaped Shells () 摘要:This paper dealt with the influence of residual stress on the dimensional instability of 7075 aluminum cone-shaped shells. Finite element method was introduced to calculate residual stress distributions in 7075 aluminum cone-shaped shells during conventional heat treatment (CHT) and deep......
