Abstract Model updating of dynamical systems has been attracting much attention because it
has a very wide range of applications in aerospace, civil, and mechanical engineering, etc …

Wind turbines are structures predominantly subjected to dynamic loads throughout their
period of life. In that sense, fatigue design plays a central role. Particularly, support structure …

A dual implementation of the Kalman filter is proposed for estimating the unknown input and
states of a linear state-space model by using sparse noisy acceleration measurements. The …

The characterization of vibration-fatigue strength is one of the key parts of mechanical
design. It is closely related to structural dynamics, which is generally studied in the …

The establishment of a Digital Twin of an operating engineered system can increase the
potency of Structural Health Monitoring (SHM) tools, which are then bestowed with …

An algorithm is presented for jointly estimating the input and state of a structure from a
limited number of acceleration measurements. The algorithm extends an existing joint input …

Offshore wind turbines are exposed to continuous wind and wave excitation. The monitoring
of high periodic strains at critical locations is important to assess the remaining lifetime of the …

Many of the civil structures experience significant vibrations and repeated stress cycles
during their life span. These conditions are the bases for fatigue analysis to accurately …

This paper presents a joint input-state estimation algorithm that can be used for the
identification of forces applied to a structure and for the extrapolation of the measured data …

In this study, a novel dual implementation of the Kalman filter proposed by Eftekhar Azam et
al.(2014, 2015) is experimentally validated for simultaneous estimation of the states and …
