Yield Locus: Overview

Learning Outcomes for this Section

After completing this section, you should be able to:

  • provide a definition of the yield locus
  • explain why yield locus is important
  • explain the influence of the anisotropy in sheet metal forming
  • know the experimental methods used to determine the yield locus
  • know the advantages and limits of the different yield criteria
  • used in the theoretical models the most appropriate yield criterion
  • analyse the sheet metal forming processes

Pre-Requisites

Before starting, it is important that you are familiar with the following terms: % elongation to failure; rolling; strain; stress; yield stress; Youngs Modulus; elastic deformation; plastic deformation; Hooke's law; ductility; formability; proof stress; plastic strain; flow curves; stress-strain diagrams; BCC; crystal system; elastic strain; FCC; forming; hardening; hoop stress; isotropic; shear; shear stress; work-hardening; shear modulus;
