Test-FEA Integration
Overview
Integrating test and analysis enables synergistic processes
from which the entire engineering team can benefit. Some
examples:
-
FEA results can be used to optimize the experimental
setup (pretest analysis)
-
Mixed numerical-analytical methods are used to quickly
and reliably identify otherwise only approximately known
structural properties (e.g. joint stiffness), material
properties, and loading (non-destructive, indirect,
testing).
-
Test results are used as reference data to validate
and refine a finite element model (error localization,
correlation analysis, model updating). Unknown or badly
known physical properties can be identified and uncertainties
in finite element models better assessed.
-
Hybrid models that contain partially FE models and
partially test models can be developed to build more
complete models that include all essential components
while maintaining a good balance between model size
and performance.
By better exploiting the combined test and analysis data,
engineering staff and management will gain more confidence
in the simulations they increasingly need to rely on for
design optimization, acoustics, fatigue analysis and so
on. They will also gain expertise for future modeling, build
up reusable knowledge and more rapidly acquire essential
skills like engineering judgment.
