ABSTRACT An effective design method to control the welding distortion of a pressure vessel constructed by HY-80 steel, especially thick plate, have been established using experiment, measurement data and FE analysis. It is found that the major factors affecting the distortion of the pressure...

... plates. Then, Thermo-Elasto-Plastic (TEP) FE analysis was carried out to predict the out-ofplane bending deformation generated by induction heating, which has a good agreement with it by measuring. With the integration of computed plastic strains caused by induction heating, elastic FE analysis...

...) method have been suggested. Among them, a GE/EPRI method is one of general estimation approaches based on finite element (FE) analysis, where material behavior is assumed to be characterized by the Ramberg-Osgood (R-O) relation. In GE/EPRI approach, plastic influence functions used to calculate fully...

Abstract In order to assess the structural capacity of grouted connections subject to bending moment loading, a finite element (FE) analysis procedure is adopted for the analysis of a grouted connection in a large diameter monopile support structure used in an offshore wind turbine. The model...
