Shape memory effect and superelasticity in a strain glass alloy.
The shape memory effect and superelasticity are usually found in alloys exhibiting spontaneous martensitic transformation. Thus it is hard to imagine that such interesting effects can appear in a system without a martensitic transformation. In this Letter we show shape memory and the superelasticity effect in a nonmartensitic Ti48.5Ni51.5 alloy, which has no martensitic transformation but under...
متن کاملStrain rate sensitivity of Cu with nanoscale twins
The strain-rate sensitivity of ultrafine-crystalline Cu with different concentrations of nanoscale growth twins is investigated using tensile strain rate jump tests. Higher twin density leads to enhanced rate sensitivity, which decreases mildly with increasing strain rate and strain. Mechanisms underlying these effects are explored through post-deformation transmission electron microscopy. 2006...
متن کاملStrain rate sensitivity of skin tissue under thermomechanical loading.
There have been limited studies addressing the thermally dependent mechanical properties of skin tissue, although this can contribute to a variety of medical applications. To address this, an experimental study on the tensile behaviour of pig skin tissue under different thermal loading conditions and different mechanical stretching rates was performed. The results indicate that there is a signi...
متن کاملStrain-rate sensitivity of porcine and ovine corneas.
Knowledge of strain-rate sensitivity of corneal tissue is important for improving the understanding of the tissue's response to mechanical actions and the accurate numerical simulation of corneal biomechanical behaviour under the effects of disease and surgery. In the study, fresh and well-preserved porcine and ovine corneal buttons were subjected to uniaxial tension loads with seven different ...
متن کاملOn the negative strain rate sensitivity of Hadfield steel
The digital image correlation (DIC) technique was utilized in conjunction with mechanical experiments carried out at different strain rates to study the negative strain rate sensitivity (NSRS) in face-centered cubic (fcc) Hadfield steels. The results shed light onto the variation of local strain fields and serrations in the stress– strain curves of Hadfield steels as a function of strain rate w...
