Inputs are linear stress or strain for this SN based technique.

This allows critical locations, load combinations and associated design ncoee factors to be readily identified. This enables the ability to interpolate multiple material data curves for factors such as mean stress or temperature.

ANSYS nCode DesignLife: Fatigue Failure Analysis

The Composite Analysis option allows users to evaluate the strength of a structure against industry standard composite failure criteria. Biaxial 3D Multiaxial Auto-correction. Safety Factor enables tutoriials calculation of stress based factors of safety.

Engineers without fatigue expertise can evaluate modified product designs to determine the updated product life. Animating displacements from FE results or animation files display structural deformation under load. They then ran the thermal-stress analysis again with the designlice 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.

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

Commercial truck owners needing weight and fuel economy savings are considering the benefits of a single wide-base wheel. Stress gradient corrections FKM Guidelines User defined Critical distance Enables vibration specification data to be entered, edited, and viewed.

The stress tensor for each layer and section integration point through the thickness is read by DesignLife from FE results. Biaxial 3D Multiaxial Auto-correction Mean stress corrections: See how our customers are using our software: The same structural stress technique used for seam welds is used in WholeLife to determine the structural bending and membrane stresses at the weld.

Includes a batch interface program to simplify the running of distributed jobs.

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

Python scripting is also available for defining custom fatigue methods and material models. Vibration Manager Enables vibration specification data to be entered, edited, and viewed. ANSYS nCode DesignLife contains the most up-to-date methods and simulation tools to make tugorials fatigue vesignlife as accurate and easy as possible. Time histories due to applied loads can be extracted for direct correlation with your measured strain or displacement data.

Manufacturing effects can be accounted for by using equivalent plastic strain in the unloaded component. The following methods can be used individually or combined to give the most conservative result: The Strain Gauge Positioning option calculates the optimum position and number of gauges required to enable the subsequent reconstruction of applied load histories.

Simulate vibration tests driven by random PSDswept sine, tutodials 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 dwsignlife typical composite ones.

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 desigmlife data to be entered, edited, and viewed.

The theoretical basis of the method was developed by the Volvo Group 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. Fatigue analysis process Once created, the fatigue process can be captured and reused. The Seam Weld option enables the fatigue analysis of seam welded joints including fillet, overlap, and laser welded joints.

Introduction to ANSYS nCode DesignLife

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 desgnlife cycles quasi-static or dynamic. A standard database with fatigue properties for many commonly used materials is included. Although this is primarily a CAE based analysis, the same method may also be applied to measured stress data.

Includes the ability to interpolate multiple material data curves for factors such as mean stress or temperature. Further options are also provided to account for stress gradients and surface finishes. Uses specific material parameters calculated from tensile and torsion tests.

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. Select from a pre-populated library of geometries or supply custom stress intensity factors.
