Distributed Processing enables a DesignLife analysis running in batch mode to be distributed across multiple computers or nodes of a computer cluster.

Multiple threads can also be used to speed up the translation phase of the analysis by splitting the translation into multiple processes. Want to learn more? The following courses feature hands-on examples with DesignLife: The Adhesive Bonds option enables durability calculations on adhesive joints in metallic structures.

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. 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.

The primary application of the Stress-Life SN method is high-cycle fatigue long lives where nominal stress controls the fatigue life. Processing threads enable you to get finished results from raw inputs in faster.

Manufacturing effects can be accounted for by using equivalent plastic strain in the unloaded component. 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.

A standard database containing over vibration entries is included. 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.

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.

Includes the ability to interpolate multiple material data curves for factors such as mean stress or temperature. Material inputs are standard mean stress corrections or user-specified Haigh diagrams to assess durability.

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

Select from a pre-populated library of geometries or supply custom stress intensity factors. The Short Fibre Composite option uses stress-life fatigue calculations for anisotropic materials andys as glass fibre filled thermoplastics. High tutoriald fatigue methods: Biaxial 3D Multiaxial Auto-correction Mean stress corrections: 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.

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. See how our customers are using our software: Inputs are linear stress or strain for this SN based technique.

Safety Factor enables the calculation of stress based factors of safety. In addition, selected location loading paths may be visually compared with the material failure envelope. 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.

Python scripting is also available for defining custom fatigue methods and material models. Enables vibration specification data to be entered, edited, and viewed. Vibration Manager Enables vibration specification data to be entered, edited, and viewed.

The Composite Analysis option allows users to evaluate the strength of a structure against industry standard composite failure criteria. Stress gradient corrections FKM Guidelines User defined Critical distance Enables vibration deeignlife 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 deslgnlife matrix or fibre stresses as well as typical composite ones.

Enables you to rapidly solve jobs by using the combined processors of many machines. Crack Growth Provides a complete fracture mechanics capability using industry standard methodologies for specified locations on an FE tutorrials.

Further options are also provided to account for stress gradients and surface finishes. Includes new optimised and spot weld methods.

Fatigue analysis process Once created, the fatigue process can be captured and reused. Simulate complex loading scenarios using any time domain method static or modal superposition, duty cycles, etc. Although this is primarily a CAE based analysis, the same method may also be applied to measured stress data. Includes a batch tutorialx program to simplify the running of distributed jobs.

Material models can also be defined using general look-up curves. The following methods can be used individually or combined to give the most conservative result: DesignLife provides methods to intelligently identify weld lines in the FE model, thus simplifying the process of setting up a fatigue job.

Biaxial 3D Multiaxial Auto-correction. Uses specific material parameters calculated from tensile and torsion tests. Since the fatigue calculation at each model location is effectively independent, the benefit to adding additional processing threads is very scalable. Download the latest version. 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.

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

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. The stress tensor for each layer and section integration point through the thickness is read by DesignLife from FE results.
