Why do we need FEA?

Predict performance for planned use

Predict potential failure with predictable abuse

Evaluate & correct observed failure

Improve performance & safety of a known design

Improve cost/weight of a known design

Develop new & innovative concepts

Gain insight into design concepts or directions

Modeling decisions should be driven by goals
3
Why FEA is so powerful
 Basic engineering equations describe stress
 Supplement basic engineering equations with
stress concentration factors from a structures
text (Roark) to determine peak stress
 Engineering equations no longer sufficient to
determine peak stress - FEA is best choice
