Abstract [en]

A further assessment of the IIW numerical and experimental test RSDP Round Robin Initiative, Phase 1 and Phase 2 is presented. Focus is on the weld process specification, and the importance ofuse of as realistic as possible weld process parameters in the weld simulations. Considerable interpretation is often required of the weld designer and of the FE modeller when simulatinga weld process. The paper demonstrates, on the IIW RSDP round Robin benchmarks, that with interpretation and judgement, Computational Welding Mechanics using a variety of models and approaches is possible. Difficulties in interpretation could be substantially reduced through the use of industrial methods of specification, weld process specifications (WPS). For this reason, the authors recommend that all benchmarks follow the standards and definitions used in internationally recognised industrial standards. For the Phase 1 benchmark three-pass butt welded pipe case, which was a designed case for weld simulations, rotationally symmetric and fully 3D results are presented for temperatures, deformations and stresses. These results are compared with IIW benchmark results, and differences caused by weld process parameters and material modelling (for the mechanical analysis) are discussed.For the Phase 2 benchmark two pass butt welded coupon plate case, experimental results are available. The incomplete documentation from the weld experiment compared to realistic WPS is discussed. 3D thermal results coupled with generalised plane strain 2D results for temperatures, deformations and stresses using correct WPS and realistic material data are presented and compared with IIW benchmark results. SFor both Benchmarks the LS-Dyna FE software was used, with a major modification being a modified Goldak heat source model.
