• Resumen

  • This article focuses on the development of a finite elements model of an adaptive composite panel with embedded shape memory alloy actuators. It is firstly shown that a combination of shell, beam and link elements could be employed to model the panel. A simplified version of the Likhachev model is then employed as the constitutive relation for the actuators. Several experimental tests were successfully carried out on a prototype to validate the model and to demonstrate the possibility of controlling the panel shape. Further works should consider improving the technique employed for reading the actuators� temperature during experimental tests.
