The Seam Weld option enables the fatigue analysis of seam welded joints including fillet, overlap, and laser welded joints. Crack Growth Provides a complete fracture mechanics capability using industry standard methodologies for specified locations on an FE model. Commercial truck owners needing weight and fuel economy savings are considering the benefits of a single wide-base wheel. 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.
Approximate calculations of the strain energy release rate are made at the edge of the adhesive and, desinglife comparison to the crack growth threshold, a safety factor is calculated. Vibration Manager Enables vibration specification data to be entered, edited, and viewed.
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.
A standard database containing over vibration entries is included. Stress gradient corrections FKM Guidelines User defined Critical distance Enables vibration specification data to be entered, edited, and viewed. The Thermo-Mechanical Fatigue TMF option provides solvers for high temperature fatigue and creep by using stress and temperature results from finite element simulations.
Material models can also be defined using general look-up curves. Includes new optimised and spot weld methods. Find training Request quote Contact us.
ANSYS nCode DesignLife
This allows critical locations, load combinations and associated design reserve factors to be readily identified. In addition, selected location loading paths may be visually compared with the material failure envelope.
Animating displacements from FE results or animation files display structural deformation under load. Enables you to rapidly solve jobs by using the combined processors of many machines. Includes a batch interface program to simplify the running of distributed jobs.
nCode DesignLife – CAE Fatigue Analysis Software – nCode
Engineers without fatigue expertise can evaluate modified product designs to determine the updated product life. Uses specific material parameters calculated from tensile and torsion tests.
The Composite Analysis option allows users to evaluate the nxode of a structure against industry standard composite failure criteria. Select from a pre-populated library of geometries or supply custom stress intensity factors. 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.
Biaxial 3D Multiaxial Auto-correction. The following courses feature hands-on examples with DesignLife: 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.
Simulate vibration tests driven by random PSDswept sine, sine dwell or sine-on-random loading Predict damage and 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.
Duty cycles can be defined by selecting from and building multiple cases. The same structural stress technique used for seam welds is used in WholeLife to determine the structural bending and membrane stresses at the weld. Material inputs are standard mean stress corrections or user-specified Haigh diagrams to assess durability.
Enables vibration specification data to be entered, edited, and viewed. See how our customers are using our software: 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. This enables the ability to interpolate multiple material data curves for factors such as mean stress or temperature. Manufacturing effects can be accounted for by using equivalent plastic strain in the unloaded component.
