November 28, 2020Journals Vol1. No1
ABSTRACT
Time-invariant plastic deformation of Steel, ST 60 Mn, locally produced by the Delta Steel complex, Aladja, Delta State, Nigeria, has been studied using a tensometer as the main instrument and regression as the tool of analysis. Empirical equations relating some design parameters and the relevant parameters pertaining to the steel under uniaxial tension have been proposed with a known factor of safety. This is necessary for the predication and formulation of design criteria. The results are justified upon testing the significance of the regression models.
Keywords: Plastic deformation, prediction models, design criteria, factor of safety.
