Development of a Practical Straightening Simulation for Welded Structures Using Inherent Strain Method

KnE Engineering, 2018
Welding is the most widely used assembly method available to industries in the construction of metal structures, ships, and offshore platforms. However, this method always produces a certain amount of distortion that will not only degrade the performance but also increase the building cost of the structure, and it should be straightened.
