Sheet Necking-III. Strain-Rate Effects

  • J. W. Hutchinson
  • K. W. Neale


The effect of material strain-rate dependence on necking retardation is examined for biaxially-stretched sheets. Rate-dependent versions of both flow theory and deformation theory are employed in an analysis of the growth of long-wavelength nonuniformities. Material strain-rate sensitivity is seen to substantially increase the predicted limit strains beyond their corresponding values for time-independent material response. We also discuss the influence of strain-rate dependence on imperfection- sensitivity and forming limit curves.
