Forced vibration and hygrothermal analysis of composite laminated beams under the action of moving loads

The dynamic response of simply supported glass/epoxy composite beams subjected to moving loads in a hygrothermal environment is carried out using the general purpose finite element program ANSYS. The moving load model and the hygrothermal incorporation are validated separately by reproducing results available in the literature. The hygrothermal effect is introduced by using empirical relations for degrading the material stiffness properties of the matrix. The corresponding ply properties are calculated using the rule of mixtures. A parametric study is conducted by varying the fiber volume fraction and the fiber orientation of the angle plies in the laminate. The results indicate that the dynamic magnification factors generally increase due to hygrothermal effects but all the laminates considered do not behave in a similar manner. Thus it is possible to minimize the environmental effect by judiciously selecting the laminate configuration.
