Abstract

Using advanced beam models based on the Carrera Unified Formulation, this paper presents an analysis of a damaged ta- pered aircraft structure. Results obtained from static and free vibration analyses are presented to evaluate the evolution of the stress and the modal behaviour in a multi-component damaged structure. This 1-D model is able to modify the material propri- eties, then the stiffness, at the local level. In this way, many types of local and global damage can be introduced into the structure. The results show the capability of the present model to obtain with a low computational cost, displacements, stresses and vi- bration characteristics of damaged structures making him a good candidate for design and maintenance tools.
