| Abstract: | The hysteretic behavior of a new-typed shape memory alloy (SMA) damper, cone shape memory alloy damper, is studied by numerical analysis and tests. Based on the SMA double-line constitutive relation, the hysteretic behavior of cone SMA damper is analyzed by the numeric nonlinear finite method. And a conclusion is drawn that the cone shape memory alloy damper's hysteretic constitutive relation can be simply piece-wise linearization one. The tests include SMA line constitutive tests, fatigue tests and cone SMA damper performance tests. The results of tests agree almost with the numeric analysis results and the ones by ANSYS programs, which show that shape memory alloy have a good superelastic properties. |
