On the understanding of damping capacity in SMA: From the material thermomechanical behaviour to the structure response
Autor: Shabnam Arbab Chirani, Aleksandr E. Volkov, Guillaume Helbert, Margarita E. Evard, Lamine Dieng
Publikováno v: Journal of Intelligent Material Systems and Structures. 32:1167-1184
Superelastic Shape Memory Alloys (SMAs) provide a high damping capacity due to the hysteretic motion of the inter-phase boundaries during the martensitic transformation. They have demonstrated their ability to control vibrations of SMA-based Civil En
