Active vibration control of flexible linkage mechanisms using shape memory alloy fiber-reinforced composites

A three‐dimensional model describing stress‐temperature induced solid phase transformations: thermomechanical coupling and hybrid composite applications

“…This result can be reached inducing prestress in the structure through the constrained recovery of the martensitic wires [23][24][25] or exploiting the increment of the elastic modulus during the transformation from martensitic to austenitic phase [26,27].…”

“…Up to now, in our knowledge, a big effort has been devoted to investigate experimentally the behaviour of always new invented composites [52][53][54], while only few researchers tried to predict numerically the experimental response and to design new devices. Among them, Venkatesh et al [27] use a simple beam finite element to predict active vibration control possibilities for planar mechanisms with Ni-Ti reinforced composite; Thompson et al [55] use standard finite element analysis to investigate the active buckling control of stiffened panels by embedded SMA rods; Ro et al [56] propose a finite element model to study the static and dynamic characteristics of Ni-Ti-reinforced composite plates; Hurlbut et al [57] implement a 3D SMA constitutive model within a shell based finite element code and study a passive vibration isolator; Benzaoui et al [58] study experimentally and numerically the behaviour of a basic actuator consisting in a single Ni-Ti SMA wire loaded by a mass; de Blonk et al [59] model the deflection of a flexible rod with embedded two way shape memory actuators; Lagoudas et al [60] model a thermoelectrically cooled thin SMA layer extensional actuator; Ostachowicz et al [61] present finite element governing equations and solution procedures to study natural frequencies of SMA fibre-reinforced composite plate; Su et al [62] propose a 2D constitutive model for a SMA reinforced composite laminated plate; Baz et al [63] study experimentally and numerically the shape control of a SMA reinforced composite beam through SMA strips thermally trained to provide and memorize controlled transverse deflections; Lau et al [64] present an analytical model for the evaluation of natural frequencies of glass fibre composite beams with embedded SMA wires. These works suggest that a properly developed computational tool can be useful to support the design of advanced hybrid composites exploiting the SMA features.…”

Finite element analysis of the random response suppression of composite panels at elevated temperatures using shape memory alloy fibers

“…It is also being studied for use in active vibration control of beams 10,11 and large space structures 12 . Active vibration control of exible linkage mechanisms using SMA ber-reinforced composites has been investigated by Venkatesh et al 13 . Acoustic transmission and radiation control through the use of SMA bers in a hybrid composite was presented by Liang and Anders 14,15 .…”

Smart material thermal characterization: NiTi shape memory alloy embedded in a resin epoxy matrix

“…fibres have more difficulties to spread, for a major reason : the thermomechanical behaviour of S.M.A. is not enough known, particularly when temperature changes during a test heating with the joule's effect, although a lot of important works have been published in this field [3][4][5][6][7].…”
