Thermo-mechanical Tensioning: A Distortion Mitigation Tool for Shipbuilding Industry
Abstract: Thin plates are widely used in ship building to lower the weight of the hull structure so as to have a gain in pay load as well as to improve fuel efficiency. But the fabrication of the structures involving the thin plates suffers weld induced buckling because of their lower critical buckling strength. So, there is a need to mitigate these weld induced buckling distortions by employing proper distortion control …
