Multiple threads can also be used to speed up the translation phase of the analysis by splitting the translation into multiple processes.

Introduction to ANSYS nCode DesignLife

Stresses from a complete finite element model are analyzed in a single analysis process. It uses an integrated approach for modeling fatigue over the entire ncodf of a component – from the very early stages to final fracture – to give more accurate determination of weld lives particularly for complex geometries.

Simulate complex loading scenarios using any time domain method static or modal superposition, duty cycles, etc. Manufacturing effects can be accounted for by using equivalent plastic strain in the unloaded component.

Includes new optimised and spot weld methods. Short Fibre Composite module features: The Strain-Life method is applicable to a wide range of problems including low-cycle fatigue with the local elastic-plastic strain controls the fatigue life. Dang Van is a multi-axial fatigue limit criterion and is a method of predicting the endurance limit under complex loading situations. The same structural stress technique used for seam welds is used in WholeLife to determine the structural bending and membrane stresses at the weld.

Adhesive bonds are modeled with beam elements and grid point forces are used to determine line forces and moments at the edge of the glued flange. Although this is primarily a CAE based analysis, the same method may also be applied to measured stress data. The Short Fibre Composite option uses stress-life fatigue calculations for anisotropic materials such as glass fibre filled thermoplastics. Applications include components that are both mechanically and thermally loaded such as vehicle exhaust systems and manifolds.


Vibration Manager Enables vibration specification data to be entered, edited, and viewed. 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. Hutorials models can also be defined using general look-up curves.

Structural stress at the weld toe, the hot-spot stress can be estimated by the extrapolation of the surface stress at points near the weld Supports BS welding standard, together with required material curves Enables vibration specification data to be entered, edited, and viewed. Python scripting is also available for defining custom tutirials methods and material models.

The Seam Weld option enables the fatigue analysis of seam welded joints including fillet, overlap, and laser welded joints. The primary application of the Stress-Life SN method is high-cycle fatigue long lives where nominal stress controls the fatigue life. 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. In addition, selected location loading paths may be visually compared desigmlife the material failure envelope.

Animating displacements from FE results or animation designoife display structural deformation under load. See how our customers are using our software: The Thermo-Mechanical Fatigue TMF option provides solvers for high temperature fatigue and creep by using stress and temperature results from finite element simulations.

This approach substantially reduced engineering costs and helped E-Z-GO get the new design into production faster. Commercial truck owners needing weight and fuel economy savings are considering the benefits of a single wide-base wheel.

This enables the ability to interpolate multiple material data curves for factors such as mean stress or temperature. Engineers without fatigue expertise can evaluate modified product designs to determine the updated product life.

Material inputs are standard mean stress corrections or user-specified Haigh diagrams to assess durability. Biaxial 3D Multiaxial Auto-correction. Download the latest version. The stress tensor for each layer and section integration point through the thickness is read by DesignLife from FE results.

The theoretical basis of the method was developed by the Volvo Group and the testing and software implementation was carried out as part of a collaborative research project with partners including Jaguar Land Rover, Coventry University and Warwick University. High temperature fatigue methods: Time histories due to applied loads can be extracted for direct correlation with your measured strain or displacement data.

Inputs are linear stress or strain for this SN based technique. Stress gradient corrections FKM Guidelines User uttorials Critical distance Enables vibration specification data to be entered, edited, and viewed. The following methods can be used individually or combined to give the most conservative result: Biaxial 3D Multiaxial Auto-correction Mean stress corrections:
