Finite element model updating: Multiple alternatives
Engineering Structures, 2008 Abstract This paper focuses on the model updating of complex structural systems. Traditional model updating techniques optimize an objective function to calculate one single optimal model that behaves similarly to the real structure and represents the physical characteristics of the structure.

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Finite Element Model Updating of Reinforced Concrete Beams with Honeycomb Damage
Archives of Civil Engineering, 2012 Honeycombing is one of the common damage that can occur in concrete structures. Literature and studies on this phenomenon are, however, limited. The objective of this study was to propose a method of detecting honeycombing damage in a reinforced concrete

Elastic–Plastic Modeling and Experimental Characterization of Granular Jamming Actuators
Advanced Engineering Materials, EarlyView.Granular jamming enables rapid switching between soft and rigid mechanical states. Here, a reduced‐order elastic‐perfectly‐plastic beam framework captures pressure‐dependent loading, unloading, residual deformation, and hysteresis in jammed beams, while matching three‐point bending experiments across materials and geometries. The framework links design

A Modified Eigenstructure Assignment Technique for Finite Element Model Updating
Shock and Vibration, 1996 This article deals with an extended application of the constrained eigenstructure assignment method (CEAM) to finite element model updating. The existing formulation is modified to accommodate larger systems by developing a quadratic linear optimization ...
