• 2014:30 Modelling Approaches to C-14 in Soil-Plant Systems and in Aquatic Environments

  Substantial expertise on carbon biogeochemistry already exists in the fields of plant physiology and aquatic ecology and therefore is it beneficial to draw on this to identify the important issues. A paper ... programme was published in Radiocarbon Journal. Further studies on C-14 (including modelling, model inter-comparisons, and experimental work) have been on-going by individual BIOPROTA member organisations and continued...

• 2009:16 Influence of Hardening Model on Weld Residual Stress Distribution

  Weld residual stresses have a large influence on the behavior of cracks growing under normal operation loads and on the leakage-flow from a through-wall crack. Accurate prediction of these events is important ... present report is the result of an effort to acquire and to develop the latest research results in the field of WRS and especially the influence of hardening model. The choice of hardening model has been the...

• 2017:22 Effect of weld repairs on residual stresses in nickel base dissimilar metal welds

  affect the residual stresses through e.g. increased tensile stresses and increased plastic straining on the surfaces of the piping in contact with the light water reactor environment. This may in turn reduce ... by numerical simulation with two dimensional axi-symmetric assumptions. Conclusions are drawn based on comparison of the weld residual stresses before and after weld repair. The results show that the inside...
