TWI Industrial Member Report Summary 350/1987
By J R Gordon and R H Leggatt
Background
This report presents the results of a series of wide plate tests on 10mm thick parent material and welded aluminium panels. The results are compared with predictions obtained using a reformulated CTOD design curve approach, a collapse modified strip yield model, a CTOD reference stress model, and the CTOD estimation scheme published by EPRI. The conditions at maximum load in the wide plate tests were predicted using both maximum load toughness and driving force/R-curve methods. The analyses of the welded wide plate specimens were performed with and without residual stresses.
