Parametric Sensitivity Analysis of Curing Deformation of Angle-Ply Fiber Metal Laminates
Abstract:
In the process of studying the curing deformation behavior of fiber metal laminates (FMLs) subjected to thermal stress, there are some discrepancies between analytical models and experimental results for the room-temperature stable configuration. The main reason is the uncertainty of the parameters in the analytical calculation. In present paper, a parametric sensitivity analysis of the influence of Young’s modulus, Poisson’s ratio, thermal expansion coefficients, ply thickness, ply angle and temperature difference on the cured stable configuration is carried out to identify the most sensitive properties. Accurate characterization of these sensitive properties and precise control of manufacture process can reduce the discrepancies and obtain a more accurate prediction model. It is believed that the present study can be helpful of guiding the design and manufacture of the FMLs in the engineer application.
