This enables the ability to interpolate multiple ncodw data curves for factors such as mean stress or temperature. A standard database with fatigue properties for many commonly used materials is included. Crack Growth Provides a complete fracture mechanics capability using industry standard methodologies for specified locations on an FE model.

Stress gradient corrections FKM Guidelines User defined Critical distance Enables vibration specification data to be entered, edited, and viewed. 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. The following courses feature hands-on examples with DesignLife: A standard database containing over vibration entries is included.

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. Enables you to rapidly solve jobs by using the combined processors of many machines.

This approach substantially reduced engineering costs and helped E-Z-GO get the new design into production faster. 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.

The output from the analysis is expressed as a safety factor rather than fatigue life. Dang Van is a multi-axial fatigue limit criterion and is a method of predicting the endurance limit under complex loading situations. This feature makes it easy to create a composite duty cycle with repeats.

The Strain Gauge Positioning option calculates the optimum position and number of gauges required to enable the subsequent reconstruction of applied load histories. Biaxial 3D Multiaxial Auto-correction Mean stress corrections: Time histories due to applied loads can be extracted for direct correlation with your measured strain or displacement data. Duty cycles can be defined by selecting from and building multiple cases. Inputs are linear stress or strain for this SN based technique.

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.

The primary application of the Stress-Life SN method is high-cycle fatigue long lives where nominal stress controls the fatigue life.

High temperature fatigue methods: Approximate calculations of the strain energy release rate are made at the edge of the adhesive and, by comparison to the crack growth threshold, a safety factor is calculated.

The same structural stress technique used for seam welds is used in WholeLife to determine the structural bending and membrane stresses at the weld. Simulate vibration tests driven by random PSDswept sine, sine dwell or sine-on-random loading Predict damage tutoriaps life per layer and integration point Incorporate results of manufacturing simulation including fibre orientation tensors or residual stresses Model local fatigue properties based on microstructure orientation tensor and stress state Calculate fatigue based on principal stresses or critical plane — including stresses calculated from FE-Digimat and multiaxial stress states Choice of fatigue property model – SN curve interpolation or interface to Digimat Use of homogenized matrix or fibre stresses as well as typical composite ones.

Includes a batch interface program to simplify the running of distributed jobs. The Strain-Life method is applicable to a wide range of znsys including low-cycle fatigue with the local elastic-plastic strain controls the fatigue life. Download the latest version.

Python scripting is also available for defining custom fatigue methods and material models. Select from a pre-populated library of geometries or supply custom stress intensity factors. Enables vibration specification data to be entered, edited, and viewed. Short Fibre Composite module features: DesignLife provides methods to intelligently identify weld lines in the FE model, thus simplifying the process of setting up a fatigue job.

Commercial truck owners needing weight and fuel economy savings are considering the benefits of a single wide-base wheel.

Manufacturing effects can be accounted for by using equivalent plastic strain in the unloaded component. Material inputs are standard mean stress corrections or user-specified Haigh diagrams to assess durability.

Product options containing functions for virtual shaker testing, fatigue of welds, vibration fatigue, tutogials growth detection, fatigue of composites, thermo-mechanical fatigue analysis and more are described below. Includes new optimised and spot weld methods.

Simulate complex loading scenarios using any time domain method static or modal superposition, duty cycles, etc. 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.

The stress tensor for each layer and section integration point through the thickness is read by DesignLife from FE results. Distributed Processing enables a DesignLife analysis running in batch mode to be distributed across multiple computers or nodes of a computer cluster.

Material models can also be defined using general look-up curves. The Adhesive Bonds option enables durability calculations on adhesive joints in metallic structures. The Composite Analysis option allows users to evaluate the strength of a structure against industry standard composite failure criteria.

Mechanical loads that vary at a different rate to the temperature variations can also be combined. See how our customers are using our software: The following methods can be used individually or combined to tugorials the most conservative result: Rather than limiting this evaluation to a small number of load cases or steps, stresses can be assessed by using the chosen failure criteria throughout realistic duty cycles quasi-static or dynamic.

Fatigue analysis process Once created, the fatigue process can be captured and reused.
