Extracting true stresses and strains from nominal stresses and strains in tensile testing
Strain, Volume 57, Issue 6, December 2021., 2021 Abstract Seemingly a simple task, the extraction of the flow curve (true stress vs. true plastic strain) from nominal stresses and strains in standard tensile testing still has its unsolved points. This study addresses two of them: (i) in materials without yield point phenomenon (or generally in the region of homogeneous plastic deformation), the true ...

steel research international, Volume 92, Issue 9, September 2021., 2021 More than 1200 heats are used so as to investigate the benefits of the powder lime injection in a 90 t electric arc furnace (EAF) and compared with the traditional addition of lime in lumps. Savings above expectations are observed for electric consumptions and lime charged, also reducing CO2 emissions for both the production of structural and special ...
