... this process, the in-plane shrinkage deformation is decoupled from the bending deformation. Using the thermo-elastic-plastic finite element method, we study the characteristics of the double-sided heating processing under the conditions of different process parameters and different initial curvatures...

... ABSTRACT For modern shipbuilding, line heating is widely employed as an effective method to form complex double-curvature plates, and the shrinkage control method is the key to form the target plate. Taking sail plate forming as an example, heating simulation is realized by thermal elastic...

... blocks in the parallel part, twisting of the block is often observed. So far, there is no theoretical explanation why it happens. According to the Authors understanding, the distortion of the welded structure is produced by two causes. One is the local shrinkage introduced by welding, such as transverse...

... will not change appreciably. To validate the two schemes ISM and i-ISM, experiment on a fillet welding model was carried out and three deformation components namely longitudinal shrinkage, transverse shrinkage and angular distortion were measured after welding. Analysis by conventional FEM, and ISM were...

... calibration of the errors caused by the out-of-plane displacement. In this paper, the measurement accuracy of the proposed method for in-plane and out-of-plane deformation is discussed through the application of a bead-on-plate welding test. The proposed method can measure transverse shrinkage and angular...

... ABSTRACT: Desiccation shrinkage, residual effective stress measurement, unconfined compression, and consolidation tests were performed. The tests have been performed on two separate sets of overconsolidated samples subjected to mechanical unloading or desiccation, to examine the common...
