Paper Abstract

This work describes modeling of non-linear damping behavior in hybrid beam structures with SMA embedded layers. The dependency of the intrinsic damping capacity of SMAs on the strain is simulated through modeling of material’s hysteresis cycle. The hysteresis cycles and the corresponding loss-factors have been investigated through uniaxial tensile test and have been reproduced and validated by numerical simulation. To do so, a phenomenological hysteresis model has been developed and implemented in ABAQUS through UMAT interface. Finally, the method was used to simulate the damping of hybrid beam structures with SMA embedded layers and the results were compared with experimental data.
