Simcenter 3D Durability

The best way to predict a product’s strength and durability

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

Eliminate over- or under-designed components 

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

Enabling a more efficient and safe physical validation

Virtual test rig experiments facilitate the analysis of the impact of individual load events on component damage. Such analysis also permits the flexibility to define your specific load scenarios for each of the components, thereby saving testing time.

Include manufacturing and assembly aspects in durability analysis

New materials and manufacturing processes often have an important influence on fatigue behavior. With Simcenter 3D, one can take into account such manufacturing defects while performing durability analysis.

Design right the first time

To perform fatigue analysis in an efficient way, durability modules provide access to:

  • Test data such as load data, test schedule definitions, etc.
  • Simulation data, such as multibody results and finite element simulations of the digital twin
  • State-of-the-art fatigue simulation methods
  • Fatigue-specific postprocessing

Providing a platform for multidiscipline simulation

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

Industry applications

Aerospace and defense

Simcenter 3D is used to predict mechanical system fatigue life for landing gears, control mechanisms, slat tracks and other critical assemblies. Local stress concentrations are identified based on all possible combinations of local load conditions to address durability problems long before prototypes are built. A wide range of methods can localize weak spots and assess fatigue life.

Automotive and transportation

Simcenter 3D is used to execute fatigue-life assessments on body frames, panels, cross-members and door systems as well as on sunroofs, latches, and locking systems. The Simcenter 3D Durability module also enables a high degree of accuracy for specific seam and spot weld analyses. Advanced numerical durability predictions can be applied to engines, powertrain parts, engine brackets, gearbox chain heels, and exhaust lines 

Industrial machinery

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 efficiently optimized. Simcenter 3D Durability can be used to determine rotor base fatigue life in large rotating machines.


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