Due to the structural parameters and pseudoelastic effect the device provides the self-centering ability and good damping properties. These features were experimentally verified in a prototype composed of four 1.5 mm diameter pseudoelastic NiTi SMA wires. There was studied a damping properties of device under cyclic loading in the wide range of frequencies from 0.001 to 2 Hz and displacement amplitude in the range of 3 – 9 mm. To stabilize the functional properties of SMA wires the device had been loaded for 50 cycles before testing. © 2022 The Authors. Published by ELSEVIER B.V.

Introduction Due to pseudoelastic properties appearing above A f (austenite finish temperature), shape memory alloys ( Ćwikła (2013)) have been widely used for damping devices to reduce the dynamic loading of bridges (Ozbulut et al. (2011), Torra et al. (2012)), structural elements of buildings (Dolce et al. (2005), Silva et al. (2015)) under operational loading or earthquakes conditions (Dolce and Cardone (2001)). These applications are mentioned in certain standards (Eurocode 8 (2005), International Code Council (2006)). 20 e 1st Virtual International Conference “In service Damage of Materials: Diagnostics and Prediction” Study of cyclic response of SMA based damping device Volodymyr Iasnii a *, Lukasz Sobaszek b , Petro Yasniy a a Ternopil Ivan Puluj National Technical University, Faculty of Engineering of Machines, Structures and Technologies Ternopil, Ukraine b Lublin University of Technology, Mechanical Engineering Faculty, Department of Production, Lublin, Poland
