Component Fatigue

LMS Virtual.Lab Component Fatigue is a complete solution to accurately assess the fatigue performance of individual components in one single, integrated simulation environment. By combining component loads derived from prototype measurements or multi-body simulations, FE-based stress results and cyclic fatigue material parameters, engineers can predict fatigue hotspots and fatigue life, and optimize the component design.

LMS Virtual.Lab Component Fatigue is a complete solution to accurately assess the fatigue performance of individual components in one single, integrated simulation environment. By combining component loads derived from prototype measurements or multibody simulations, FE-based stress results and cyclic fatigue material parameters, LMS Virtual.Lab Component Fatigue allows engineers to predict fatigue hotspots and corresponding fatigue life, and optimize the component design for fatigue performance.

The straightforward interface offers a clear built-in workflow and set-up templates to guide users through the process. With seamless access to FE meshes and stresses, automatic Nastran and Ansys driving, and direct component load importing, users can quickly prepare fatigue analyses all within the same environment.

LMS Virtual.Lab Component Fatigue offers all the fatigue-life analysis capabilities of the popular LMS FALANCS solver, including assessment of lowcycle fatigue, high-cycle fatigue and infinite life, stress gradient correction,

below-surface fatigue as well as seam and spot weld analysis.

With dedicated post-processing functionalities, engineers can quickly identify and solve fatigue life problems, and experiment with multiple design options. Parametric analyses let users identify innovative design solutions before physical prototyping.

durability engineering process FE models LMS FALANCS seam welds 3 Audi 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.

BMW uses Virtual Test Rigs for Loads Prediction

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.
