...Joël Brezillon; Gerald Carrier; Martin Laban This paper presents a multidisciplinary optimization framework developed by the authors and applied to small-size supersonic aircraft. The multidisciplinary analysis suite is based on the combination of low (empirical) and high-fidelity computational...

... by assessing the experimental lifetime of the connections, and comparing them to experimental results. Then, the structural reliability of the module is evaluated over the target aircraft predicted useful lifetime, comparing the First Order Reliability Method (FORM) and Monte-Carlo Simulation (M-CS...

... greater than that of the constitutive material. The contact mechanism and the induced stress relief increase the stretching capacity of the contact-aided cellular structures by as much as 100%. Experiments are conducted to validate the models, and good agreement is found. A high-strain morphing aircraft...

The system-level consistency constraint formulation used in this investigation avoids the computational difficulties normally associated with convergence in collaborative optimization. The consistency constraints are formulated...
