Fatigue study of partially overlapped circular hollow section K-joints. Part 2 : experimental study and validation of numerical models

In the second part of this study, the reliability of the geometrical models and the mesh generation procedure developed in Part 1 are validated by comparing the modelling results with full scale tests results. Static tests were applied to study the stress concentration factors while fatigue tests we...
