(2016) Free vibration of laminated composite plate with shape memory alloy fibers. Latin American Journal of Solids and Structures 13(2): Investigation of vibration mitigation of stay cables Jun 03, 2019 · This paper addresses the vibration mitigation of stay cables by using superelastic shape memory alloy (SMA) dampers. A closed form solution of the additional equivalent modal damping ratio of a combined stay cable/SMA damper system is formulated when the combined stay cable/SMA damper system vibrates with a single mode. Mechanical and Vibration Characteristics of Laminated Aug 01, 2009 · Currently, there is a great interest in the study of shape memory alloy (SMA) composites, since SMA wires with a small diameter have become commercially available. Many potential uses have been found for SMA composites in shape control, vibration control, and for the realization of structures with improved damage tolerance. In this work, two types of SMA-hybridized composites are presented
