This work presents an experimental study related to the mechanical performance of a special design spring fabricated with a superelastic shape memory alloy (SMA-SE). For the experimental testing. the spring was coupled in a rotor machine. aiming to attenuate the mechanical vibration when the system went through a natural frequency without any external power source. https://jjepuadsctazvv.bloginwi.com/68598528/a-new-species-and-new-records-of-oxysarcodexia-townsend-diptera-sarcophagidae-from-brazil
