Influence of geometry and loading conditions on the dynamics of martensitic fronts
Arkadi Berezovski

 
Abstract
    Damping capacity of SMA damping devices is simulated numerically under distinct geometry and loading conditions. Two-dimensional numerical simulations are performed on the basis of a phenomenological model of dynamics of martensite-austenite phase boundaries. Results of the simulations predict the time delay and the value of the stress transferred to other parts of a construction by a damper device.
 
Key Words
    shape-memory alloys; martensitic phase transformation; moving phase boundary; numerical simulation; specific damping capacity.
