    durability engineering process FE models LMS FALANCS seam welds 3Audi Moves Forward with Early Durability Predictions 

    Audi has achieved considerable progress in supporting the durability design of upcoming models by using a hybrid approach that effectively combines testing and simulation. This new methodology, engineered in conjunction with LMS, enables Audi to streamline its durability engineering activities. Audi has improved its ability to predict and adapt the durability of key components with the LMS FALANCS solver, even before the start of the physical prototyping phase.

    The “Holy Grail” for many durability engineers is to reliably predict where and when their products will break – long before the first hardware prototype is built. To do so would dramatically shorten the durability process and help engineers to get higher quality products to market faster and more cheaply. A recent break-through by LMS, working in conjunction with engineers from BMW in Germany, has made significant advances towards that ultimate goal.

    Advanced research, conducted by ASCO, LMS and the VUB, is directed at how to re-design safety-critical components of airplanes. The team is applying life-prediction methods on virtual prototypes, using optimized test scenarios on the physical prototype and applying on-line damage-detection techniques during the physical test. This project represents a critical shift in the application of advanced LMS TecWare durability technologies from the automotive industry to aerospace.
