Durability Simulation

Simcenter™ 3D software offers a distinct set of tools to support fatigue design at all stages of development. This includes easy-to-use wizards for strength and fatigue in the design phase, fatigue information in the actual simulated part, detailed analysis of complex load scenarios including welds and connections, and new materials and manufacturing processes.

  • Realistically simulate the durability performance of complex connections and welded joints

  • Predict component loads and optimize fatigue performance at the system level through the load transfer path approach

  • Take advantage of new materials and manufacturing processes using precise fatigue methods

Shorter development cycles and ever-increasing quality requirements have pushed the test-based approach to durability to the limits. Evaluating and refining durability performance by simulation methods is the only valid alternative. Siemens Digital Industries Software's Simcenter 3D durability modules provide access to state-of-the-art analysis methods, allowing engineers to interactively assign loads to a model. The solution enables efficient analysis of seam and spot welds, as well as new methodologies for composite materials.

Analyze the loads acting in the critical regions and improve the load flow of the application points that have the most influence in the critical areas, which is much better than just reinforcing around the critical area.

Virtual testbed experiments make it easy to analyze the impact of individual load events on component damage. This analysis also allows you the flexibility to define your specific load scenarios for each of your components, saving testing time.

New materials and manufacturing processes often have an important influence on fatigue behavior. With Simcenter 3D, you can take these manufacturing influences into account when performing durability analysis.

To perform fatigue analysis efficiently, durability modules provide access to:

  • Test data such as load data, test schedule definitions, etc.

  • Simulation data such as multibody results and digital twin finite element simulations

  • State-of-the-art fatigue simulation methods

  • Fatigue-specific post-processing

The Simcenter 3D Durability Solution is part of a larger multidisciplinary simulation environment and is integrated with Simcenter 3D Engineering Desktop at the core for centralized pre/post processing for all Simcenter 3D solutions. This integrated environment helps you achieve faster CAE processes and streamline multidisciplinary simulations that integrate durability and other disciplines such as stress and strain of structural solutions, load prediction using motion solution, and prediction of nonlinear behavior of short or long fiber composites. to tight integration for damage-tolerant design.

Automotive and transport

Industrial machinery



Simcenter 3D is used to predict the service life of mechanical systems such as landing gear, control mechanisms, slat mats and other critical assemblies, but especially also for turbines. Local stress concentrations are identified based on all possible combinations of local load conditions to resolve durability issues long before prototypes are built. A wide range of methods can locate weaknesses and assess fatigue life.

Simcenter 3D is used to perform fatigue assessments on body structures, panels, cross members and door systems, as well as sunroofs, latches and locking systems. The Simcenter 3D Durability module also allows a high degree of accuracy for specific seam and spot weld analysis. Advanced numerical durability predictions can be applied to engines, power train parts, engine mounts, gearbox chain jumps and exhaust lines.

In industrial applications, achieving cost efficiencies depends on critical parts that are typically subjected to large dynamic multiaxial load cases. Any metal component subjected to dynamic loading cycles can be optimized efficiently. Simcenter 3D Durability can be used to determine rotor base fatigue life on large rotating machines.

Durability and full function are especially important for medical devices. Simcenter 3D Specialist Durability is used to prevent failure of civic systems.

Simcenter 3D Specialist Durability connection modeling allows you to have a digital twin for miles of welds performed on ship structures. For high-end yachts with many composite materials, the Simcenter 3D Specialist Durability Composite Fatigue module facilitates state-of-the-art analysis.




The Simcenter 3D Durability wizard is a simulation wizard for calculating the fatigue life of mechanical components subjected to load cycles. This solution is performed after users have calculated a state of stress from static loading using a finite element (FE) solver . The durability algorithms in the wizard are based on the crack initiation method for fatigue analysis.


Simcenter 3D Advanced Durability software helps validate the product's structural integrity throughout its lifecycle under simple or complex loading conditions. Expert analysts use this solution to perform in-depth fatigue analysis and life calculations to help them determine product durability based on Simcenter Nastran, Simcenter 3D Response Dynamics, MSC Nastran, ANSYS and Abaqus solutions. Based on the crack initiation method for fatigue calculation, the user can choose various service life criteria and can take into account mean stress effects, notch effects, case hardening effects and biaxial stress effects. Fatigue and strength safety factors, fatigue life, and damage results are visualized as contour plots.




Simcenter 3D Specialist Durability Modeling provides a rich and intuitive toolset for preparing solutions, submitting them to the solver , and post-processing durability results. It allows the configuration of complex durability scenarios with many finite element cases and load history. Durability solutions can be configured using supplied parameters or configured to follow standard user procedures.



Simcenter 3D Specialist Durability Solver is the basic solver  for specialist fatigue analysis. It can be run on the same computer or independently in batch mode . It provides all standard durability methodologies but can be easily extended with any fatigue methodology due to the unique aperture through user defined fatigue methods.




Simcenter 3D Specialist Durability Composite Fatigue provides a unique methodology for analyzing short and continuous fiber composites. It can incorporate stiffness reduction and stress redistribution during the fatigue life of composites under complex load situations. New technologies reduce the effort needed to test the parameterization of methods.



Simcenter 3D Specialist Durability for Connections allows you to configure and conduct special spot welds and seam weld analysis runs. Welds are made from connections modeled in Simcenter 3D, defined in xMCF format, or detected in existing meshes.

Configuration and load analysis are performed using the same tools as Simcenter 3D Specialist Durability Modeling and can even be mixed in an analysis case.
