A Simplified Analysis of Residual Stress at Welded Joints between Plate and Penetrating Pipe

Evaluation of through thickness residual stress in multipass butt welded joint by using inherent strain

“…Thermal elastic-plastic numerical analysis methods have proven useful for examining the details of the inelastic behaviour during welding and residual stresses of structural components, while the inherent strain approach, which is equivalent to eigen strain, has been effective for quick evaluation by using inverse elastic calculating from measured strains to find residual stresses. [29][30][31][32][33][34][35][36][37][38][39][40][41][42][43] Supercomputers are often utilised for the lengthy numerical calculations necessary for thermal elasticplastic analysis. Three-dimensional computations are becoming possible to apply to actual components, 14,22,23,25,27 but the calculation time is still enormous.…”

Numerical and experimental validation of residual stresses of laser‐welded joints and their influence on the fatigue behaviour

“…The double ellipsoidal model proposed by Goldak et al was used for modelling heat input from the welding torch in the thermal analysis. Mochizuki and his co‐workers developed analytical evaluation methods for welding residual stress by using inherent strain analysis and thermal elastoplastic FE analysis . The residual stress distribution determined using these methods agreed well with each other.…”

Analysis of residual stresses in a long hollow cylinder

“…(18) for r ¼ k. By making use of Eqs. (3) and (13), condition (20) can be written in terms of the key functions only:…”

“…A vast majority of the existing experiment-calculated methods employ numerical [11e18] or approximate [19,20] procedures. However, for efficient analysis of the residual stresses, as well as for solving inverse elasto-plastic problems (which necessarily occur when one applies certain experiment-calculated methods), exact analytical solutions are required.…”
