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-Motor Works的工程師使用ANSYS nCode DesignLife疲勞分析軟體計算高工作週期疲勞安全係數。他們隨後對新設計再次運行熱應力分析,將應力結果匯出到nCode DesignLife,然後把結果與材料模型及該產品在工作中預計會承受的重複性載荷的描述相結合。nCode DesignLife會在ANSYS Workbenc採集該資料、資料流程和參數,然後使用應力-壽命方法開展綜合性疲勞分析。 查看案例
