MSC Fatigue


Mechanical systems that fail while in operation cause serious problems for all parties involved. Manufacturers are faced with high warranty costs and liabilities, but more importantly, the safety of persons operating faulty cars, trucks, aircraft, or machinery may be at risk. To reduce the risk that their products will fatigue prematurely or unexpectedly, manufacturers may:

  • Over-design parts using much higher than necessary margins of safety, which adds weight & cost.

  • Rely heavily on physical fatigue tests to accurately predict failure conditions and life expectancy, which increases costs and time-to-market, and limits the number of conditions and operating scenarios that can be tested.


  • As a key component in your Virtual Product Development (VPD) process, MSC Fatigue enables you to quickly and accurately predict how long your products will last under any combinations of time-dependent or frequency-dependent loading conditions, and to optimize your products for weight and shape.

    The MSC Fatigue family offers an integrated suite of products that grow with your needs:

    • Core products, such as Basic, Pre & Post, Strain Gauge, and Utilities, provide basic functionality for building, testing, reviewing, and improving your products from a durability standpoint.
    • Add-on products, such as Fracture, Multiaxial, and Vibration, extend the capabilities of the Core products.
    • Industry-specific products, such as Weld and Wheels, offer fatigue calculations tailored to particular industries or applications.
