The Fatigue Wizard software enables CAE engineers of any experience level to utilize results of a finite element analysis to carry out sophisticated and accurate fatigue life calculation. CAE engineers with over 30 years combined experience and knowledge of finite element analysis and durability assessment developed it.
The Fatigue Wizard leads you through the steps necessary to perform complex fatigue life calculation. You can view results as life or safety factors using the Fatigue Wizard post processor, or export and view in Autodesk® Simulation. With minimum effort and time, you can use the Fatigue Wizard to generate customizable reports.
Fatigue Wizard can perform sophisticated fatigue life analyses, from conventional stress-based analyses to low cycle strain-based analyses with plasticity correction. Mean stress corrections can be accounted for using standard methods. Endurance modifiers such as surface finish, temperature, and so on, are all available. For a complete list of the capabilities within the Fatigue Wizard, follow the features link.
Fatigue Wizard can perform fatigue calculations using stress results from multiple load cases. Results from multiple load cases can be scaled individually using separate load histories of up to 30000 points, and analyzed as a combined load case. Alternatively, stress states from individual load cases can be used in sequence to produce the cyclic stress history.
Successful fatigue analysis depends entirely on accurate material data. Fatigue Wizard ships with an extensive material database for stress life curves (SN) and strain life curves (EN), and component data for welded joints to BS7608. You can add to the database as data becomes available.
Fatigue Wizard includes post processing tools. An OpenGL results post processor is included within the wizard interface. You can view life contours or safety factor contours before you step back to perform 'what-if' analyses.
Fatigue Wizard additional 'advanced' forms. With analysis options, you can control the mean stress corrections and FEA stresses to use. You can control the portion of the FE model to analyze, based on a ranked maximum stress range.
You can perform fatigue calculations using equivalent stresses, such as signed Von Mises, tresca, and maximum absolute principal stress. Alternatively, a critical plane approach is implemented using resolved surface normal or shear stress.
Fatigue Wizard offers several choices to aid speed of calculation. You can select the choices individually depending upon the required speed, reliability, and desired output. You can analyze all of the model, or parts of the model. You can analyze the model selectively based on your defined 'groups,' or by a given percentage of nodes based on a ranked nodal maximum stress range.
