Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Shape memory alloys (SMAs) have been widely used in smart structures due to their adaptive properties. Their thermomechanical coupling can provide vibration attenuation or actuation providing a desired dynamical response. Chaos control methods can provide the stabilisation of unstable periodic orbits allowing one to choose a convenient response. Besides, it can promote bifurcation control that can avoid undesirable responses. This work investigates the chaos control of smart structures employing time-delayed feedback control to perform orbit stabilisation. A two-bar truss is of concern using thermal actuation of SMA elements. Thermal constraints defined by energy equation are investigated, showing the real possibilities of this kind of control. Numerical results show situations related to controller constraints, defining its range of applicability. Control strategy potentialities are discussed showing unstable periodic orbit stabilisation, exchangeable target control and bifurcation control.
