Improved Craig–Bampton Method Implemented into Durability Analysis of Flexible Multibody Systems
Actuators, 2023 The Craig–Bampton method is frequently applied in most commercial multibody dynamic software. Nevertheless, the Craig–Bampton modes only represent the free-free modes in flexible multibody systems.

Journal of Marine Science and Engineering, 2020 Analytical method using Rayleigh–Ritz method has not been widely used recently due to intensive use of finite element analysis (FEA). However as long as suitable mode functions together with component mode synthesis (CMS) can be provided, Rayleigh–Ritz ...
