With the implementation of environmental protection, sustainable development and
conservation-oriented policies, components and parts of thin-walled welded tubes have …

A welded connection consists of three main material zones, the base material (BM), the heat-
affect zone (HAZ), and the weld metal (WM). The strength of HAZ depends on the BM grade …

The girth-weld joint of a pipeline can be divided into three parts: base metal, heat affected
zone, and weld metal. This study investigates the local mechanical properties of X80 and …

The digital image correlation (DIC) method has become popular to characterize the local
constitutive properties distribution especially for the welded joints. Although the evaluation of …

A laser-welded TA15 titanium alloy tube with outer diameter of 40 mm and thickness of 2 mm
was fabricated successfully by hot U–O forming process combining with laser beam welding …

Severe non-uniform deformation occurs in the forming of tailor-welded blanks (TWBs) with a
large difference in properties or shell thickness of base materials, which lowers deformability …

The coupon specimen with a transverse butt weld in the middle could be used for
determining local constitutive properties of the heat-affected zone (HAZ) and the weld metal …

Due to remarkable difference in material properties of Tailor Welded Blanks (TWBs), when
subjected to uniform forming load, severe non-uniform metal flow and strain localization …

A continuum damage model (CDM) based on local hardness in welds is developed to
predict fracture of welded tubes. A regression function of hardness distribution in the welds …

Heterogeneous constitutive properties across the welded zone affect the accuracy of the
simulation of the fracture and large plastic deformation of the welded steel joints. Neglecting …
