Development of a finite element model updating technique for estimation of constituent level elastic parameters of FRP plates

Constituent Parameter Identification of Braided Composite Based on Sensitivity Analysis

“…Calculating the sensitivity matrix through the direct derivation and finite difference methods, the inverse method coupling with relative sensitivity analysis was proposed to identify the constituent parameters of a braided composite. The finite forward difference was used [13] S FD ij =…”

Experimental and numerical approaches for structural assessment in new footbridge designs (SFRSCC–GFPR hybrid structure)

“…Cost function and optimization algorithm Finite Element Model Updating (FEMU) strategy can be employed in a wide range of applications [24][25][26]: (i) design; (ii) simulation; (iii) prediction; and (iv) damage identification.…”

Model updating of uncertain parameters of carbon/epoxy composite plates from experimental modal data

“…Apart from the direct interest of having determined morerealistic mechanical characteristics of the plates, this reference model can be used for both, the prediction of the dynamic behaviour and the detection and localization of defects induced in structures composed by this kind of plates. Some of the contributions of this study are the high accuracy reached in the experimental modal analysis, with up to 22 modesidentified, number much higher than usually reached in this kind of works [18][19][20][21][22], and the automatization of mode pairing needed for model updating algorithms considering such a great number of modes during optimization process. Additionally,it is also innovative the use of extensive Monte Carlo Simulations (MCS) to perform sensitivity analysis of the potentially updated parameters.…”
