A New FEA Element can Adjust Itself

The Cessna Citation Mustang will benefit from the multicharacter finite element.
Noran Engineering devised the tension-only element because of some 200 FEA load cases Cessna engineers had to run on aircraft structures.
A newly developed quad element lets aircraft designers cut the amount of manual tweaking once needed for some of the 200 FEA load cases they deal with. The new element transforms from one able to carry tension with shear, to one for tension only. And depending on other loads, a third transformation-is possible.
