For most metallic materials, the surface mechanical attrition treatment (SMAT) resulted in a substantial increase in the yield strength, but accompanied by a certain decrease in the ductility. However, the regulating of the yield strength and ductili

When an elongated columnar shape memory alloy (SMA) element buckles, in some cases it exhibits negative stiffness. This post-buckling negative stiffness can be repeatedly used as SMAs can recover their shape. This property has potential application t
