Finite Element Modeling

ASD’s finite element structural modeling experience includes construction of math models from structural design information and working existing models received from associate contractors. All finite element modeling is conducted with the end goal of achieving reduced dynamic math models that are highly correlated with test data, e.g., modal survey test. To this end, ASD’s finite element math model construction strictly conforms to “modeling the structure” as realistically as possible. With this modeling discipline, ASD has achieved exemplary success, on multiple programs, in the generation of test correlated structural math models. Such successful correlation precludes the use of “response uncertainty factors” in the certification for flight readiness process, i.e., the certification criteria remains more realistic.
