Processing threads enable you to get finished results from raw inputs in faster. Material inputs are standard mean stress corrections or user-specified Haigh diagrams to assess durability.

Enables you to rapidly solve jobs by using the combined processors of many machines. This feature makes it easy to ncoed a composite duty cycle with repeats. Biaxial 3D Multiaxial Auto-correction.

Select from a pre-populated library of geometries tutoials supply custom stress intensity factors. Enables vibration specification data to be entered, edited, and viewed. The Strain Gauge Positioning option calculates the optimum position and number of gauges required to enable the subsequent reconstruction of applied load histories.

This allows critical locations, load combinations and associated design reserve factors to be readily identified.

Fatigue Analysis using FEA Results Design for Durability Attendees looking to learn more about nxode background of fatigue theory are encouraged to attend our 2-day course called Practical Fatigue Theory.

Further options are also provided to account for stress gradients and surface finishes. Download the latest version.

The Adhesive Bonds option enables durability calculations on adhesive joints in metallic structures. Distributed Processing enables a DesignLife analysis running in batch mode to be distributed across multiple computers or nodes of a computer cluster.

Mechanical loads that vary at a different rate to the temperature variations can also be combined. The following courses feature hands-on examples with DesignLife: 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. 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.


Vibration Manager Enables vibration specification data to be entered, edited, and viewed. Biaxial 3D Multiaxial Auto-correction Mean stress corrections: Safety Factor enables the calculation of stress based factors of safety. This approach substantially reduced ncide costs and helped E-Z-GO get the new design into production faster.

Includes a batch interface program to simplify tutroials running of distributed jobs. Want to learn more? 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.

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. DesignLife provides methods to intelligently identify weld lines in the FE model, thus simplifying the process of setting up a fatigue job.

The Seam Weld option enables the fatigue analysis of tutoriaos welded joints including fillet, overlap, and laser welded joints. A standard database with fatigue properties for many commonly used materials is included. Manufacturing effects can be accounted for by using equivalent plastic strain in the unloaded component. Although this is primarily a CAE based analysis, the same method may also xnsys applied to measured stress data.

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

A standard database containing over vibration entries is included. Python scripting is also available for defining custom fatigue methods and material models. Since the fatigue calculation at each model location is effectively independent, the benefit to adding additional processing threads is very scalable.

The output from the analysis is expressed as a safety factor rather than fatigue life. Stress gradient corrections FKM Guidelines User defined Critical distance 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.


Duty cycles can be defined by selecting from and building multiple cases. The Composite Analysis option allows users to evaluate the strength of a structure against industry standard composite failure criteria. Animating displacements from FE results or animation files display structural deformation under load.

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.

Dang Van is a multi-axial fatigue limit criterion and is a method of predicting the endurance limit under complex loading situations.

The Thermo-Mechanical Fatigue TMF option provides solvers for high temperature fatigue and creep by using stress and temperature results from finite element simulations.

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. 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.
