The primary application of the Stress-Life SN method is high-cycle fatigue long lives where nominal stress controls the fatigue life. See how our customers are using our software: Applications include components that are both mechanically and thermally loaded such as vehicle exhaust systems and manifolds. 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.

Rather than limiting this evaluation ttorials a small number of ndode cases or steps, stresses can be assessed by using the chosen failure criteria throughout realistic duty cycles quasi-static or dynamic.

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

Duty cycles can be defined by selecting from and building multiple cases.

Manufacturing effects can be accounted for by using equivalent plastic strain in the unloaded component. Biaxial 3D Multiaxial Auto-correction. 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.

Based on the results of the finite element analysis, fatigue dssignlife estimation anys durability testing, the new utility vehicle frame design was released for production. A standard database with fatigue properties for many commonly used materials is included. 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 deskgnlife 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.

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

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

Product options containing functions for virtual shaker testing, fatigue of welds, vibration fatigue, crack growth detection, fatigue of composites, thermo-mechanical fatigue analysis and more are described below. Python scripting is also available for defining custom fatigue methods and material models.

Engineers without fatigue expertise can evaluate modified nclde designs to determine the updated product life. The stress tensor for each layer and section integration point through the thickness is read by DesignLife from FE results.

Fatigue analysis process Once created, the fatigue process can be captured and reused. In addition, selected location loading paths may be visually compared with the material failure envelope. Includes a batch interface program to simplify the running of distributed jobs. Simulate complex loading scenarios using any time domain method static or modal superposition, duty cycles, etc. This approach substantially reduced engineering costs and helped E-Z-GO get the new design into production faster.

Crack Growth Provides a complete fracture mechanics capability using industry standard methodologies for specified locations on an FE model. Multiple threads node also be used to speed up the translation phase of the analysis by splitting the translation into multiple designliife.

Uses specific material parameters calculated from tensile and torsion tests. Select from a pre-populated library of geometries or supply custom stress intensity factors.

Commercial truck owners needing weight and fuel economy savings are considering the benefits of a single wide-base wheel. This method is widely used as a key design criteria for engine and powertrain components like crankshafts, camshafts and pistons.

The Adhesive Bonds option enables durability calculations on adhesive joints in metallic structures. Includes new optimised and spot weld methods. Short Fibre Composite module features: Inputs are linear stress or strain for this SN based technique. Want to learn more? Enables vibration specification data to be entered, edited, and viewed.

Biaxial 3D Multiaxial Auto-correction Mean stress tutoriala Stresses from a designlifd finite element model are analyzed in a single analysis process. ANSYS nCode DesignLife contains the most up-to-date methods and simulation tools to make predicting fatigue life as accurate and easy as possible.
