A family of Craig–Bampton methods considering residual mode compensation

作者：

Highlights：

• A family of Craig–Bampton methods considering residual modes is formulated.

• The nth-order Craig-Bampton+ method (HCBn+) method is newly proposed.

• Through numerical examples, HCB1+ achieved better performance than HCB1.

• However, HCB2+ and HCB3+ showed lower performance than HCB2 and HCB3.

• The limitation of O'Callahan's approximation is revealed with numerical examples.
