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 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 Thermo-Mechanical Fatigue TMF tutoria,s provides solvers for high temperature fatigue and creep by using stress and temperature results from finite element simulations. Although this is primarily a CAE based analysis, the same method may also be applied to measured stress data. They then ran the thermal-stress analysis again with the new design, exported the stresses to nCode DesignLife, and combined the results with a material model and a description of the repetitive loading that the product is expected to undergo during operation.

Mechanical loads that vary at a different rate to the temperature variations can also sesignlife combined. 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.

The output from the analysis is expressed as a safety factor rather than fatigue life. Crack Growth Provides a complete fracture mechanics capability using industry standard methodologies for specified locations on an FE model.

This method is widely used as a key design criteria for engine and powertrain components like crankshafts, camshafts and pistons. 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. 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.

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. A standard database containing over vibration entries is included. Material inputs are standard mean stress corrections or user-specified Haigh diagrams to assess durability.

The Adhesive Bonds option enables durability calculations on adhesive joints in metallic structures. Select from a pre-populated library of geometries or supply custom stress intensity factors. The stress tensor for each layer and section integration point through the thickness is read by DesignLife from FE results.

Animating displacements from FE results or animation files display structural deformation under load. Want to learn more? Engineers without fatigue expertise can evaluate modified product designs to determine the updated product life. Commercial truck owners needing weight and fuel economy savings are considering the benefits of a single wide-base wheel. The following courses feature hands-on examples with DesignLife: Inputs are linear stress or strain for this SN based technique.

The Short Fibre Composite option uses stress-life fatigue calculations for anisotropic materials such as glass fibre filled thermoplastics. 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. Short Fibre Composite module features: Time histories due to applied loads can be extracted for direct correlation with your measured strain or displacement data.

Includes a batch interface program to simplify the running of distributed jobs. See how our customers are using our software: Vibration Manager Enables vibration specification data to be entered, edited, and viewed. 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.

Manufacturing effects can be accounted for by using equivalent plastic strain in the unloaded component. The Seam Weld option enables the fatigue analysis of seam welded joints including fillet, overlap, and laser welded joints. Further options are also provided to account for stress gradients and surface finishes.

Includes the ability to interpolate multiple material data curves for factors such as mean stress or temperature. The theoretical basis of the method was developed by the Volvo Mcode 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: Python scripting is also available for defining custom fatigue methods and material models. This approach substantially reduced engineering costs and helped E-Z-GO get the new design into production faster. It uses an integrated approach for modeling fatigue over the entire lifetime absys a component – from the very early stages to final fracture – to give more accurate determination of weld lives particularly for complex geometries.

This allows critical locations, load combinations and associated design reserve factors to be readily identified. Enables vibration specification data to be entered, edited, and viewed. Distributed Processing enables a DesignLife analysis running in batch mode to be distributed across multiple computers or nodes of a computer cluster.

Biaxial 3D Multiaxial Auto-correction. Material models can also be defined using general look-up curves. The Composite Analysis option allows users to evaluate the strength of a structure against industry standard composite failure criteria. Processing threads enable you to get finished results from raw inputs in faster.

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. Simulate complex loading scenarios using any time domain method static or modal superposition, duty cycles, tutrials. Download the latest version. This ansyd the ability to interpolate multiple material data curves for design,ife such as mean stress or temperature.

Uses specific material parameters calculated from tensile and torsion tests. Duty cycles can be defined by selecting from and building multiple cases. In addition, selected location loading paths may be visually compared with the material failure envelope.
