Application of the Characteristic Time Expansion Method for Estimating Nonlinear Restoring Forces
This paper proposes a characteristic time expansion method (CTEM) for estimating nonlinear restoring forces. Because noisy data and numerical instability are the main causes of numerical developing problems in an inverse field, a polynomial to identify restoring forces is usually adopted to eliminat...
