Fracture toughness of TA31 titanium alloy joints welded by electron beam welding under constrained condition
TL;DR: In this paper, the fracture toughness of welded joints was studied and it was found that fracture toughness decreases a lot, only 70% of the fracture strength of base metal, and the fracture surface was mainly ductile fracture mechanism with a large number of dimples by SEM.

Fracture envelopes on the 3D-DIC and hybrid inverse methods considering loading history
TL;DR: In this paper, a comparative investigation of fracture envelopes constructed by 3D-DIC and hybrid inverse analyses was conducted for the DP980 1.2t steel over a wide range of loading conditions, tensile tests were conducted using three different specimens that are expected to induce certain stress states of plane strain tension, in-plane shear and uniaxial tension at the potential location for the fracture initiation.
