Void growth and interaction experiments: Implications to the optimal straining rate in superplastic forming

Modeling the influence of grain-level matrix inhomogeneity on strain localization in the presence of hard particles

“…An experimental parametric study has been performed by Mulholland et al [11,19] of uniaxial tension of Pb-Sn sheet samples containing two drilled holes aligned along the loading direction. Earlier localization and failure has been observed in their studies as the inter-hole spacing decreases.…”

Superplasticity deformation of Ti–6Al–2Zr–1Mo–1V induced by the cyclic change of strain-rate and MaxmSPD

“…The deformation behavior was first investigated by tensile test [6][7][8][9][10][11][12][13][14][15] to study the flow stress variation, elongation and the effect of process parameters on SPD. The deformation mechanism, microstructure evolution, phase transformation and recrystallization have also been studied [16][17][18][19][20][21][22][23][24]. In addition, the Finite Element simulation was conducted to model and reveal the material flow behaviors in SPD process [25][26][27][28][29][30][31].…”

Void Growth and Interaction in a Structural Aluminum Alloy: Experiments and Theory

“…One of the main observations of these works is that ductility increases with an increase in the number of holes. The experimental study by [43], also on a eutectic tin-lead alloy, revealed an increase in ductility with the number of holes up to 10 holes and a decrease thereafter. This last reference also showed that for strain-rate sensitive materials, such as superplastic materials, it is possible to control the ductility of the holed specimen by appropriately choosing the applied strain rate.…”
