The welding distortion of a plate structure during the assembly process is influenced not only by the local shrinkage due to the welding thermal cycle but also by the root gap and the misalignment. Th...
Finite element method is a powerful tool for predicting welding distortion. However, the mechanical phenomena in welding are strong non-linear transient problems and thermal-elastic-plastic FE analysi...
The residual deformation induced by welding processes becomes a cause of repair work at the subsequent process. Therefore it is necessary to manage the assembly of welded structures by estimating acc...
Though many methods are applied to solve the combinatorial optimization problem, there are many cases in which the solution can not be solved in practical computation time, even if the computer become...
This paper deals with the effect of phase transformation on the transverse shrinkage by comparing experimental data and numerical results of transverse shrinkage generated by welding. Both mild steel ...
A hull block is generally composed of skin plates, longitudinals and transverse webs as a grillage structure, and longitudinals and transverse webs are joined by fillet weld on a skin plate panel.
New type of LNG carrier with independent aluminum tanks of prismatic shape, SPB system (Self-supporting Prismatic Tank Type-B System), was developed in Ishikawajima-Harima Heavy Industries, Co., Ltd.(...
The application of washable filters for particulate respirators in shipyards is reported; the problems concerning maintenance and care of the filters are discussed in consideration of filter features.
For the same horse power of the marine desiel, to minimize the hull weight is the key factor in order to raise the steel ship speed. At present, thin high and higher tensile steel plates are widel...
