Notes:
Based on Brinson’s one-dimensional thermo-constitutive law of SMA and classical platetheory, linear non-axisymmetric vibration of uniform heated composite annular plate embeddedwith circumferential SMA fibers is investigated. Natural frequencies of the annular plates withimmovably clamped boundary condition, depending on the temperature rise are obtained by usingshooting method. The characteristic curves of first four natural frequencies of non-axisymmetricvibration versus temperature rise are plotted. Influences of the volume fraction and the initial strainof SMA on the natural frequencies of plate are analyzed. The numerical results show that, theactivation of SMA can enhance the natural frequency both in the inverse martensite transformationtemperature range and the thermal buckling temperature
