International Journal of Corrosion, Volume 2024, Issue 1, 2024.Natural tara and oak gall nut tannins, which lack corrosion inhibitive properties, were modified using gum arabic and tested against microbial corrosion induced by Acidithiobacillus thiooxidans under isothermal condition (28°C). Mild steel coated with the modified tannins was exposed to the causative under aerobic and anaerobic conditions. Based on the

Elastic-plastic defect interaction in (a)symmetrical double edge notched tension specimens [PDF]
, 2017 Interaction of defects tends to intensify their crack driving force response compared to the situation where these defects act independently. The interaction between multiple defects is addressed in engineering critical assessment standards like BS7910 ...

Design of a (mini) wide plate specimen for strain-based weld integrity assessment [PDF]
, 2011 Wide plate tension tests are commonly executed to investigate the integrity of defective welds under a uniaxial load. The specimen can be flat or curved, depending on the geometry from which it has been extracted (plate or pipe).
