A. Rochinha Model Validation on Composites: Constitutive Parameters Identification Today's computer power make
it possible to model and analyse complex mechanical systems involving
non regular geometries, multi-physics and, specially concerning the
use of new materials, nonlinear behavior and very heterogenous properties.
This unique opportunity strongly motivates the use of modelling on engineering
design and analysis, which, in turn, gives rise to a emerging field
often referred to as model validation. The central question behind it
is how accurately does the model represent reality? Such issue is crucial
when composite materials are to be used. Model validation relies on
system identification, which consists on the process of The author appreciates the contribution of his co-authors prof. Lavinia Borges (COPPE-UFRJ), Sergio.Bastos (SENAI-CETIQT)., Mariana Teixeira and Fabio (Master Students). |
