Can SolidWorks Do Fatigue Analysis?

Fatigue analysis is a crucial aspect of engineering design. It helps in determining the lifespan of components and structures under repetitive loading conditions.

SolidWorks, the popular computer-aided design (CAD) software, offers a range of powerful capabilities for design and simulation. But can it handle fatigue analysis? Let’s find out.

The Basics of Fatigue Analysis

Fatigue analysis involves assessing the structural integrity of a component or structure by analyzing its response to cyclic loading. It takes into account factors such as material properties, loading conditions, and geometry to predict the fatigue life or number of cycles until failure.

SolidWorks provides various tools and modules that enable engineers to perform comprehensive fatigue analysis on their designs. These tools are part of the Simulation package, which extends SolidWorks’ capabilities beyond traditional CAD functionalities.

Durability Assessment with SolidWorks Simulation

SolidWorks Simulation is an advanced finite element analysis (FEA) tool that allows engineers to simulate real-world conditions and evaluate the performance of their designs. It offers a dedicated module called SolidWorks Simulation Professional, which includes fatigue analysis capabilities.

With SolidWorks Simulation Professional, users can accurately predict the behavior of their designs under cyclic loads and assess their durability. The software employs sophisticated algorithms and material models to calculate stresses, strains, and fatigue life based on industry-standard methodologies such as the Stress-Life method (S-N curve).

Key Features of SolidWorks Fatigue Analysis

  • Fatigue Studies: Users can define multiple fatigue studies within a single simulation setup, allowing for efficient evaluation of different load cases or scenarios.
  • Load History: SolidWorks Simulation enables users to define load histories based on measured or simulated data, ensuring accurate representation of real-world loading conditions.
  • Material Database: The software includes a comprehensive material database with pre-defined fatigue properties for a wide range of commonly used materials. Users can also define custom materials and fatigue curves.
  • Post-Processing: SolidWorks Simulation provides detailed post-processing tools to visualize and analyze results, such as stress-life plots, damage accumulation curves, and safety factors.

The Workflow for Fatigue Analysis in SolidWorks

The process of performing fatigue analysis in SolidWorks typically involves the following steps:

  1. Create or import the CAD geometry of the component or structure to be analyzed.
  2. Define the material properties and assign them to the geometry.
  3. Create appropriate meshing for accurate analysis results.
  4. Apply loads and boundary conditions based on the intended operating conditions.
  5. Set up fatigue studies, including load history and desired analysis parameters.
  6. Run the simulation and wait for results to be calculated.
  7. Analyze the results using post-processing tools provided by SolidWorks Simulation Professional.

In Conclusion

SolidWorks is not just limited to design capabilities; it also offers powerful tools for fatigue analysis. With its dedicated simulation module, SolidWorks Simulation Professional, engineers can accurately assess the durability of their designs and make informed decisions regarding material selection, geometric modifications, or operating conditions. By incorporating fatigue analysis into their design process, engineers can ensure that their products meet performance requirements and have a longer lifespan in real-world applications.
