It is well known that fiber reinforced metal (FRM) plate warps under thermal load, if the internal fiber distribution within the matrix is biased. In this paper, a simple 1-dimensional model is established to analyze the thermal deformation of unidirectional metal matrix composite (UD-MMC) thin plate. Based on the assumptions that the plate is experiencing pure bending deformation, closed-form expressions of the plate's normal strain and bending curvature are deduced from force and moment equilibrium equation. Two examples, one-ply-fiber and four-ply-fiber lay-ups are analyzed, leading to the explicit relationship between curvature and plate parameters. The four-ply-fiber case agrees well with the full 3-D FEM simulations, proving the appropriateness of the present model. This analysis, with simplicity and relative considerable accuracy, can be applied in the design of the thermal-deformation based actuators.
