Paper presented at the The 29th International Ocean and Polar Engineering Conference, June 16–21, 2019
Paper Number: ISOPE-I-19-462
... ABSTRACT In this study, the proposed linearized inherent strain method for predicting straightening of welded structures is investigated. Thermal elastic-plastic analysis is used to compute inherent strain of a thin flat plate caused by line heating. An accurate gas heat source model is employed in...

... would be generated to make the plate produce out-of-plane displacement. There are three main ways of hot forming according to heating source forms, including line heating with flame (oxygen-acetylene flame), laser heating and high frequency induction heating. At present, the fore two hot bending forming...
