Summary
An experimental technique which employs a rapidly expanding thin ring specimen is described as it is used to determine the nucleation parameters associated with the void growth model of ductile failure. In this configuration failure is usually preceded by well defined shear bands, and the analysis technique adopted includes the appropriate band equilibrium equations. Results obtained in this study indicate that the shear band initiation is essentially independent of the strain rate, and that the growth and coalescence of voids could come much later in the deformation process.
