By combining the strength of Simcenter ‘s finite element-based solving capabilities for composites with a new durability solver approach, you can correctly analyze the influence of progressive damage so you can develop a damage-tolerant, lightweight design that can perform well under multiple loads with variable amplitudes. This approach has been proven for short and endless fiber re-enforced plastics as well as for adhesive structures.
To perform an accurate fatigue simulation, you must first create an accurate model of your system and components. Simcenter helps you quickly create your model and set up the correct fatigue-specific parameters and attributes. You can also efficiently evaluate simulation results with durability-centric postprocessing tools to understand the causes of fatigue and learn how to improve your structures and your fatigue tests early in the design phase.
Based on 30 years of experience, Simcenter’s durability solution efficiently simulates any fatigue mechanism from low-cycle fatigue to high-cycle fatigue. It uses all the finite-element solutions, static, dynamic, or transient depending on the application not restricted by the solver. It consequently makes use of intelligent algorithms to speed up the process and of parallel processing.
Easily add new methodologies for adjusting methods for new materials or new manufacturing processes or to new test results. Simcenter allows you to configure the fatigue analysis completely for different types of materials or manufacturing processes.
Using realistic loads is critical for durability analysis. With Simcenter, you can use loads obtained from several different sources, such as from physical measurement campaigns, multi-body dynamics simulations, requirement documents, or from load databases. Loads can also be time-based or frequency-based, deterministic or random, or single event or multiple events.
Hundreds of spot welds and long-running seam welds can be aspects of sheet structure used in vehicle body and suspension systems and are critical areas where fatigue-based failure can occur. Simcenter can help you confidently simulate durability performance of large flexible welded systems or complex sub-systems. For example, Simcenter automates seam-weld durability assessment sparing you the tedious task of adapting the FE mesh according to seam-weld meshing guidelines. Spot welds fatigue simulation uses the Rupp/LBF approach, CDH and a special JSAE model as well as a stress-based approach using detailed modeling.
