However, if the BM fracture can be achieved, joints strength should equal to BM strength.
The strength of joints depends on various factors; HAZ thickness, plate thickness, plate width and the strength relations of BM, HAZ and WM and so on.
To make clear the effects of these factors, we are simulating deformation behavior of joints by using 3-D finite element analysis.
