Stress gradient corrections FKM Guidelines Desivnlife defined Critical distance Enables vibration specification data to be entered, edited, and viewed. Short Fibre Composite module features: Applications include components that are both mechanically and thermally loaded such as vehicle exhaust systems and manifolds.

Time histories due to applied loads can be extracted for direct correlation with your measured strain or displacement data. Material inputs are standard mean stress corrections or user-specified Haigh diagrams to assess durability.

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. The Composite Analysis option allows users to evaluate the strength of a structure against industry standard tytorials failure criteria. Select from a pre-populated library of geometries or supply custom stress intensity factors. The primary application of the Stress-Life SN method is high-cycle fatigue long lives where nominal stress controls the fatigue life.

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

Introduction to ANSYS nCode DesignLife – FEA, CFD and Explicit Dynamics

It uses an tutorialz 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 life estimation and durability testing, the mcode utility vehicle frame design was released for production.

Python scripting is also available for defining custom fatigue methods and material models. The Adhesive Bonds option enables durability calculations on adhesive joints in metallic structures.

Product options tktorials 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.

Includes a batch interface program to simplify the running of distributed jobs. Biaxial 3D Multiaxial Auto-correction.

Simulate complex loading scenarios using any time domain method static or modal superposition, duty cycles, etc. 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.

The following methods can be used individually or combined to give the most conservative result: This approach substantially reduced engineering costs and helped E-Z-GO get the new design into production faster. The Thermo-Mechanical Fatigue TMF option provides solvers for high temperature fatigue and creep by using stress and temperature results from finite element simulations. This feature makes it easy to create a composite duty cycle with repeats.

Download the latest version. The output from the analysis is expressed as a safety factor rather than fatigue life.

Multiple threads can also be used to speed up the translation phase of the tutorizls by splitting the translation into multiple processes. They then ran the desinlife 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.

Fatigue tuutorials process Once created, the fatigue process can be captured and reused. Animating displacements from FE results or animation files display structural deformation under tutorialss. Although this is primarily a CAE based analysis, the same method may also be applied to measured stress data. High temperature fatigue methods: 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.

This allows critical locations, load combinations and associated design reserve factors to be readily identified. The Short Fibre Composite option uses stress-life fatigue calculations for anisotropic materials such as glass fibre filled thermoplastics.

The following desihnlife feature hands-on examples with DesignLife: Crack Growth Provides a complete fracture mechanics capability using industry standard methodologies for specified locations on an FE model. 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.

ANSYS nCode DesignLife

Safety Factor enables the calculation of stress based factors of safety. 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. See how our customers are using our software: Dang Van is a multi-axial fatigue limit criterion and is a method of predicting the endurance limit under complex loading situations.

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.

Mechanical loads that vary at a different rate to the temperature variations can also be combined. A standard database containing over vibration entries is included. Manufacturing effects can be accounted for by using equivalent plastic strain in the unloaded component. Distributed Processing enables a DesignLife thtorials running in batch mode to be distributed across multiple computers or nodes of a computer cluster. The Seam Weld option enables the fatigue analysis of seam welded joints including fillet, overlap, and laser welded joints.

Vibration Manager Enables vibration tutorails data to be entered, edited, and viewed.
