Robust design is a process that ensures that a given design is characterized with maximum reliability,
maximum durability, and minimum weight. The approach ensures that the performance of the considered
structural component is insensitive to small scatter or variations in material properties, manufacturing,
loads, and geometry. With the use of composites, robust design is used to prevent initial micro-racking
and initial delamination from growing to pose a threat to the integrity of the structure.

Provide design engineers with robust methodology for sizing structural components to meet requirements
for reliability, durability, and weight.
Use GENOA's multi-scale progressive failure analysis MS-PFA robust design module considering
uncertainties in material properties, manufacturing, geometry, shape, and loads. Manufacturing
variables include composite layup and ply thickness. The capability delivers optimized manufacturing
variables for maximum reliability, maximum durability, and minimum reliability. Sensitivity
analysis is used to identify critical design variables that influence the reliability, durability,
Robust design is done using any in-service loading including static and fatigue.
Relevant GENOA modules are MS-PFA Robust Design and Probabilistic Analysis Modules.
