Advantages of FEA
FEA provides some unique advantages. FEA can routinely predict the outcome of both static and dynamic experimental tests with near-perfect accuracy.
FEA is repeatable - In FEA you have a deterministic environment with complete control over the testing procedure. This enables the analyst to quickly identify and isolate the key design parameters.
FEA is safe - Experimental structural testing is a potentially dangerous activity. Certain tests involving people or other vehicles are simply too dangerous to be carried out in any other way.
FEA is inexpensive - By bringing the testing phase forward to the initial design stages, FEA limits the need for the production of expensive prototypes and the need for extensive test campaigns.
