Detailed structural validation of aerospace structures from sub-system level down to coupon level, using cutting edge finite element technology fully integrated with design

Today’s Aerospace and Defense industry is challenged by a need to significantly accelerate new programs from concept to delivery without ever sacrificing quality and safety standards. To efficiently prove that certification requirements with respect to strength and deformation are met, highly accurate methods for structural validation fully integrated with design are needed in all phases of a program. By making a scalable set of such methods available on Dassault Systèmes’ 3DEXPERIENCE platform, our solution for Sub-System Level Structural Validation contributes to increasing certification confidence in early design phases while reducing development time and cost.

Designing and certifying an aerospace structure requires structural validation at different levels – from full structure level down to coupon level. Providing appropriate methodologies for transferring load information from the full structure level down to lower levels is crucial for accurately validating the structural performance of sub-systems and individual parts. Our solution is based on best-in-class Abaqus solver technology and offers scalable structural fidelity methodologies – from linear to highly nonlinear simulations – which can be leveraged for structural validation at different levels and in different design phases.

With full integration of design and structural simulation on the 3DEXPERIENCE platform, our Sub-System Level Structural Validation solution allows for simulation-driven decision making, ultimately leading to higher product performance and reliability. Easy propagation of design updates to all simulation analysts, direct reuse of design data in structural models – such as composite or fastener data – and automation of model creation tasks are key advantages of the seamless integration with design. Moreover, the collaborative nature of the 3DEXPERIENCE platform enables multiple users or teams to simultaneously work on the creation of structural models for large sub-systems. These capabilities lead to significant improvements in engineering efficiency and accelerate the creation of large scale structural models from months to weeks.
