Succeeding to the previous work, this paper discusses nonlinear deformation behavior of antisymmetric laminate plate under centrifugal and/or temperature load. The nonlinear properties of the plate originate from large (out-plane) deformation, which influences the structure in two aspects : large strain and follower force. The first effect, acts to stiffen the structure, is considered in the present analysis by introducing Von-Karmen terms into strain expressions; the second effect, acts to soften structure, is considered as additional terms in the virtual work expressions. Results of the analysis are compared with that of nonlinear FEM analysis, it is seen that present scheme renders good numerical accuracy. For the model being considered here, the nonlinear influence of centrifugal force must be accounted at 10,000rpm, while that at temperature-rise up to 120K this influence is insignificant. The present analysis provides a good theoretical basis for the experimental plan.
