WebPrimer on the Craig-Bampton Method - NASA WebJan 19, 2024 · When doing a Craig Bampton reduction of a free body (ie no restraint is applied to the body), I would like to generate the K and M matrices of the reduced system but without the rigid body modes. For example, if the modes of my models are 0 Hz, 15 Hz, 45Hz, 55Hz, I would like my reduced model to contain only the 15 and 45 Hz. aggiecard tamu
