INTRODUCTION Welding is a major part of everyday life with applications that vary from an industrial environment to custom fabrication...

... the pipeline corrosion. In this work, we study the effect of defect geometry and density along the pipe on the local stress-strain distribution and subsequent local corrosion activity. Small strain von Mises yielding criteria is used and corrosion potential, anodic current density, and cathodic current density...

... orientation, surface roughness, and internal defects. To address the low fatigue behavior of metal AM components, there is an increase in interest in performing surface treatments such as machining or polishing on additive manufactured components. With AM’s unique potential to produce complex shapes...

... of defects that could increase the prospect of tuning the efficiency of the materials in the transportation, catalysis and mechanical reaction efficiency. Consideration of the interfaces between them could lead to improved functionalities of the materials. This paper systematically compares MoS 2...
