Built in dampers for stayed cables in bridges via SMA. The SMARTeR-ESF project: a mesoscopic and macroscopic experimental analysis with numerical simulations
(Elsevier, 2013-04)
Article
Open AccessShape Memory Alloys (SMAs) are good candidates for solid-state dampers appropriate for the oscillations of bridge stay cables because of their large recoverable strain, hysteresis and reasonable fatigue-life. This work ... -
Effects of strain aging in NiTi SMA wire for dampers
(Elsevier, 2015)
Article
Open AccessThe thermo-mechanical properties of Shape Memory Alloys (SMA) as smart materials suggest their application as actuators, but also as dampers, thanks to the high damping properties during the hysteresis of the thermo-elastic ... -
Effects of strain aging in NiTi SMA wires for dampers
(Universidad del Pais Vasco, 2014)
Conference report
Open AccessSMA NiTi wires experience evolution under constrained aging. A strain and temperature aging sequence is designed and experimented, to ascertain the functionality of the dampers exposed to weathering -
