In the field of structural dynamics, taking into account nonlinearities in models is a topical issue, which is gradually being integrated by the industrial sector. The spectacular progress in IT performance that has been taking place in recent decades justifies this growing interest. The objective is to create increasingly realistic models, which makes them more complex and nonlinear in many aspects. The computational cost of these models must be reduced as they often have a high number of degrees of freedom while maintaining the accuracy and reliability of the solutions.The work presented in this PhD thesis consists in the development of numerical methods allowing to quickly and efficiently compute large vibration problems that present var...
