DATADVANCE at DYNACOMP

Arcachon, France — DATADVANCE presented the application of MACROS tools to design and analysis of composite structures within the framework of the First Conference on Composites Dynamics DYNACOMP. The results shown proved MACROS performance and demonstrated how using MACROS can speed up the design process.

The two presented papers are result of collaborative effort between DATADVANCE, Airbus, EADS Innovation Works and Onera. The first paper, titled "Comparison of different techniques for surrogate modeling of stability constraints for composite structures", proposes two methods for approximation of stability constraints for composite structures. An extensive comparison of these methods and an in-house Airbus tool had shown that MACROS High Dimensional Approximation technique developed by DATADVANCE performs significantly better than other methods, both conventional and designed specifically for the considered problem.

The second paper, presented during the plenary session and titled "Surrogate modeling of buckling analysis in support of composite structure optimization", considers the problem of aircraft structural components optimization regarding wing, fuselage, and tail design. Solving this problem is known to be a computation intensive task requiring high performance due to computational load of mechanical strength criteria calculations. An effective optimization method is proposed, which uses surrogate models of optimization constraints (mechanical strength criteria) and had been shown to speed up the optimization reducing computation time from several days to a few hours.
