Compressive deformation and energy absorption characteristics of closed cell aluminum-fly ash particle composite foam
TL;DR: In this article, the influence of strain rate on the deformation responses is found to be very marginal; within the domain considered in the present study, and the strain rate sensitivity was measured to be low and varying in the range of 0.02-0.04 when the foam relative density is greater than 0.1.

Strain rate sensitivity of a high-strain-rate superplastic Al6061/20SiCW composite under uniaxial and equibiaxial tension
Kang Cheung Chan,G. Q. Tong +1 more
TL;DR: In this paper, the deformation behavior of Al6061/20SiCW composite under both uniaxial and equibiaxial tension was examined and a maximum elongation of about 505% was observed at an initial strain rate of 6.56×10−2 s−1 and at a temperature of 873 K. The results also show that m value is almost independent of true strain, which differs from conventional superplastic alloys.
