Davini C., Podio-Guidugli P. Is there a critical void fraction for the yield stress of metals?. In: International Journal of Mechanical Sciences, vol. 24 (12) pp. 741 - 747. Pergamon, 1982.
Lower bounds for the curve of yield stress versus void fraction in a metal for various void pressures are used, together with upper bounds from Keife and Stahlberg [1], to define the true curve. The analysis suggests that a sudden reduction of yeld stress at any specific void fraction cannot be expected.
