At 200% shear strain amplitude, the SMA wires in
all of the base isolators experience a strain greater than 10%. It
can be also observed that the strain induced in SMA wires will
not exceed 10% when the base isolator is subjected to shear strains
lower than 100%. However, at larger shear strains, the SMA wire in
the base isolator with high aspect ratio can experience as high as
27% strain.
