Yield strength tracking of UOE pipe considering various thickness-to-diameter ratios

Abundant literature was dedicated to the numerical tracking of the yield strength of cold formed pipes throughout their forming process. However, the flattening process conducted on straps sampled from the formed pipe for tensile test as well as the residual stress developed after each stage were not considered in most studies. Therefore, a simulation-based finite element analysis program was developed to replicate the UOE forming of steel pipes...
