A Tetra-Core Stress Analysis Model
Final rept. 28 May-17 Dec 1971
BOEING CO SEATTLE WA
Pagination or Media Count:
The results of a five-month analytical program are presented, describing a stress analysis method for a three-dimensional fiber composite structure. The intersections of the elements or webs of this structure form polyhedra in the form of triangular prisms, tetra-core, and truncated form of these. The finite-element model generates the elements and polyhedra automatically with an optimization routine which selects the minimum weight structure that will meet the stiffness and loads requirements.
