Predict your product’s fatigue life before you build it

ANSYS nCode DesignLife works with ANSYS Mechanical to reliably evaluate fatigue life. Using the results of finite element analysis (FEA) from ANSYS Mechanical, it calculates stresses and strains, then cumulates damage from repetitive loading to determine a product’s predicted life. You can quickly evaluate the effects of different materials and alternative geometries for new designs, and then optimize them for the product’s expected usage — long before the first prototype is built.

ANSYS nCode DesignLife, the industry-leading tool for durability analysis, gives you a comprehensive diagnostic fatigue process to predict your product’s operational lifetime. It is fully integrated into ANSYS Workbench for ease of use and smooth workflow. You can create complex loading “duty cycles” based on measurements that represent real-life forces on products, or use anticipated loading histories.

Fatigue analysis process
Once created, the fatigue process can be captured and reused. Engineers without fatigue expertise can evaluate modified product designs to determine the updated product life. Start-to-end automation avoids the majority of errors and ensures consistency, especially in large organizations in which multiple engineers might be analyzing the results.



  • Ease of Use

    ANSYS nCode DesignLife is fully integrated within the ANSYS Workbench environment, so you can define a complete fatigue process that you can apply repeatedly.

  • Extensive Fatigue Material Library

    ANSYS nCode DesignLife comes with a complete materials library to aid in building models quickly.

  • State-of-the-art Fatigue Modeling Capabilities

    ANSYS nCode DesignLife contains the most up-to-date methods and simulation tools to make predicting fatigue life as accurate and easy as possible.

Ural Diesel Motors

Ural Diesel Motors

Ural Diesel-Motor Works engineers used ANSYS nCode DesignLife fatigue analysis software to calculate high-cycle fatigue safety factors. They then ran the thermal-stress analysis again with the new design, exported the stresses to nCode DesignLife, and combined the results with a material model and a description of the repetitive loading that the product is expected to undergo during operation. nCode DesignLife captured the data, data flow and parameters in ANSYS Workbench and performed a comprehensive fatigue analysis using the stress-life approach.

E-Z-GO, a Textron Company

E-Z-GO engineers were given one week to redesign a utility vehicle frame to eliminate a bend that was causing manufacturing difficulties. Based on the results of the finite element analysis, fatigue life estimation and durability testing, the new utility vehicle frame design was released for production. This approach substantially reduced engineering costs and helped E-Z-GO get the new design into production faster. View Case Study
