    Linear, stress & thermal analysis

  • Static fatigue

    Determine the durability of structures under repeated loading, including low- and high-cycle fatigue. Measure durability by the number of cycles to failure or the cumulative damage. Loading can be simple or multi-axial.

    Fatigue is one of the most damaging failure mechanisms in all industries where dynamic loading is present, simply because concepts like peak load and maximum stress cannot be used for prediction. Fatigue life requires the long-term damage caused by multiple loads over millions of cycles. Fatigue simulation in Autodesk Nastran In-CAD software provides tools to help you to evaluate this damage and gain control over this response. Use these tools to evaluate equipment such as:

    • The fork crown on a bicycle suspension
    • Rotating shafts
    • Industrial machine equipment
    • Ship board equipment
  • Heat transfer

    Use the principles of conduction and convection heat transfer to examine designs for equilibrium temperature distribution. Predict both the temperature changes and the downstream effects.

    Thermal effects, such as temperature rise or drop-over ambient, are responsible for engines seizing and brake system failure in automobiles. Thermal expansion/contraction affects fit and operation, while stresses caused by thermal expansion/contraction can render an otherwise operational design useless.

    Thermal heat transfer, as well as thermal expansion analyses, help you to prevent assembly failure due to high-stress concentration: for example, a rotor on a brake. Use the included tools to learn how a displacement affects stresses in compressors, engines, pipes, ducting, vent supports and more.

  • Linear buckling

    Analyse designs inside Inventor software or Dassault SOLIDWORKS for buckling. Buckling may occur in areas where compression causes a loss in stiffness, which can be overlooked and have costly consequences.

    Find out if the material used for your column, beam structure or other model does not yield, then make sure that the model will not buckle under certain loads. Modify the model dimensions within your CAD environment to avoid catastrophic failure for loading conditions.

  • Linear statics

    Determine stress, strain and deformation that results from applied static loads and imposed constraints - one of the most common types of analysis. Apply loads and constraints to your parametric part. The Autodesk Nastran solver provides results that you can display in a wide variety of formats.
