Precise Time-Integration Method with Dimensional Expanding for Structural Dynamic Equations

The precise time-integration method proposed fro a linear time-invariant dynamic system can give precise numerical results approaching the exact solution at the integration points. However, difficulties arise when the algorithm is used for nonhomogeneous dynamic systems due to the inverse matrix cal...

Zusammenfassung:	The precise time-integration method proposed fro a linear time-invariant dynamic system can give precise numerical results approaching the exact solution at the integration points. However, difficulties arise when the algorithm is used for nonhomogeneous dynamic systems due to the inverse matrix calculation required.
