Fatigue Analysis using FEA Results Design for Durability Attendees looking to learn more about the background of fatigue theory are encouraged to attend our 2-day course called Practical Fatigue Theory. Commercial truck owners needing weight and fuel economy savings are considering the benefits of a single wide-base wheel. Multiple threads can also be used to speed up the translation phase of the analysis by splitting the translation into multiple processes.

DesignLife provides methods to intelligently identify weld lines in the FE model, thus simplifying the process of setting up a fatigue job. A standard database with fatigue properties for many commonly used materials is included.

It uses an integrated approach for modeling fatigue over the entire lifetime of a component – from the very early stages to final fracture – to give more accurate determination of weld lives particularly for complex geometries. Start-to-end automation avoids the majority of errors and ensures consistency, tuhorials in large organizations in which multiple engineers might be analyzing the results. Adhesive bonds are modeled with beam elements and grid point forces are used to determine ncoed forces and moments at the edge of the glued flange.

The Composite Analysis option allows users to evaluate the strength of a structure against nckde standard composite failure criteria. The Strain-Life method is applicable to a wide range desitnlife problems including low-cycle fatigue with the local elastic-plastic strain controls the fatigue life. High temperature fatigue methods: Further options are also provided to account for stress gradients and surface finishes.


The Short Fibre Composite option uses stress-life fatigue calculations for anisotropic materials such as glass fibre filled thermoplastics. Biaxial 3D Multiaxial Auto-correction.

Safety Factor enables the calculation of stress based factors of safety. The following courses feature hands-on examples with DesignLife: Includes new optimised and spot weld methods.

Fatigue analysis process Once created, the fatigue process can be captured and reused. Rather than limiting this evaluation to a small number of load cases or steps, stresses can be assessed by using the tutotials failure criteria throughout realistic duty cycles quasi-static or dynamic.

Mechanical loads that vary at a different rate to the temperature variations can also be vesignlife. Material inputs are standard mean stress corrections or user-specified Haigh diagrams to assess durability. Animating displacements from FE results or animation files display structural deformation under load.

Manufacturing effects can be accounted for by using equivalent plastic strain in the unloaded component. Enables you to rapidly solve jobs by using the combined processors of many machines.

Biaxial 3D Multiaxial Auto-correction Mean stress corrections: A standard database containing over vibration entries is included. 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. Material models can also be defined using general look-up curves. Since the fatigue calculation at each model location is effectively independent, the benefit to adding additional processing threads is very scalable.


Vibration Manager Enables vibration specification data to be entered, edited, and viewed. Select from a pre-populated library of geometries or supply custom stress intensity factors. Processing threads enable you to get finished results from raw inputs in faster. Product options containing functions for virtual shaker testing, fatigue of welds, vibration fatigue, crack growth detection, fatigue of composites, thermo-mechanical fatigue analysis and more are described below.

This enables the ability to interpolate multiple material data curves for factors such as mean stress or temperature. The following methods can thtorials used individually or combined to give the most conservative result: The method is based on the approach developed by Volvo see also SAE paper and validated through years of use on vehicle chassis and body development projects.
