Abstract

Large deformation dynamic response of linear viscoelastic temperature dependent nonhomogeneous columns is investigated under axial compressive loads and due to thermal stresses and moments. Creep buckling instabilities and probabilities of material failure are analyzed to determine column life or survival times. Optimum relaxation moduli shapes and viscoelastic functionally graded designer materials are studied to minimize thermal stress and axial load effects while concurrently lowering failure probabilities and extending survival times for columns with large deformations.
