Accordingly, design suggestions on the opening position and shape of the bulkhead structure subject...

... ABSTRACT Thermal cutting and welding are sequentially applied to components in shipbuilding, leading to the induction of coupling residual stresses during this continuous process. This results in a residual stress distribution that differs from that induced by individual processes. This study...
