Axial and Biaxial Fatigue Behavior of 6061‐T651 Cold Metal Transfer Welded Joints

Fatigue &Fracture of Engineering Materials &Structures, EarlyView.
ABSTRACT Lightweight aluminum structures in transportation systems are increasingly exposed to complex service loading, yet the fatigue performance of welded joints is still predominantly assessed using uniaxial data. In this work, the axial and biaxial fatigue behavior of 6061‐T651 aluminum alloy joints produced by cold metal transfer (CMT) welding is

Prevention and Management of Tooth Discolouration of Endodontic Origin (DEO): A State‐of‐the‐Art Review

International Endodontic Journal, EarlyView.
ABSTRACT Background Tooth discolouration of endodontic origin (DEO) refers to an undesirable change in tooth colour arising from the pulp space as a result of reactive physiological processes, pathological processes or endodontic procedures and materials. As DEO frequently affects teeth in the aesthetic zone, it may substantially impair self‐esteem and
