Extended Kalman filter for material parameter estimation in nonlinear structural finite element models using direct differentiation method

Summary This paper presents a novel nonlinear finite element (FE) model updating framework, in which advanced nonlinear structural FE modeling and analysis techniques are used jointly with the extended Kalman filter (EKF) to estimate time‐invariant parameters associated to the nonlinear material con...
