Fiber-reinforced-metal (FRM) plate generally warps under thermal load, if the fiber distribution within the plate is biased. This effect is intentionally made use of to manufacture FRM base actuators. In this paper, the 1-Dimensional beam model developed previously is utilized to analyze the thermal deformation properties of such actuators. From force and moment equilibrium equations, the formulea for normal strain (ε_0) and bending curvature (κ) of the one-column-fiber SiC/Al actuator are deduced in closed-form. Deformations of two types actuators, one-side-heating and two-side-heating, are simulated, considering large deflection and temperature distribution effects. Comparison is made between the calculation results and the experimental data. Good agreement is obtained, showing that present analysis can predict the actuator's deformation properties well.
