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

Distributed Processing enables a DesignLife analysis running in batch mode to be distributed across multiple computers or nodes of a computer cluster. High temperature fatigue methods: Further options are also provided to account for stress gradients and surface finishes. 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.

Crack Growth Provides a complete fracture mechanics capability using industry standard methodologies for specified locations on an FE model. 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.

Safety Factor enables the calculation of stress based factors of safety. Vibration Manager Enables vibration specification data to be entered, edited, and viewed.

Introduction to ANSYS nCode DesignLife

Includes the ability to interpolate multiple material data curves for factors such as mean stress or temperature. Enables vibration specification data to be entered, edited, and viewed. Material inputs are standard mean stress corrections or user-specified Haigh diagrams to assess durability.

Adhesive bonds are modeled deignlife beam elements and grid point forces are used to determine line forces and moments at the edge of the glued flange.

The same structural stress technique used for seam welds is used in WholeLife to determine the structural bending and membrane stresses at the weld. Manufacturing effects can be accounted for by using equivalent plastic strain in the unloaded component. The stress tensor for each layer and section integration point through the thickness is read by DesignLife from FE results.

Material models can also be defined using ncodd look-up curves. 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. Although this is primarily a CAE based analysis, the same method may also be applied to measured stress data.

The snsys 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. In addition, selected location loading paths may be visually compared with the material failure envelope.

This allows critical locations, load combinations and associated design reserve factors to be readily identified. See how our customers are using our software: Tutoriaps provides methods to intelligently identify weld lines in the FE model, thus simplifying the process of setting up a fatigue job. This feature makes it easy to create a composite duty cycle with repeats. 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 designllife 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.

The primary application of the Designliffe SN method is high-cycle fatigue long lives where nominal stress controls the fatigue life.

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. Short Fibre Composite module features: Multiple threads can also be used to speed up the translation phase of the analysis by splitting the translation into multiple desigblife.

Stresses from a complete finite element model are analyzed in a single analysis process. This anss substantially reduced engineering costs and helped E-Z-GO get the new design into production faster.

Fatigue analysis process Once created, the fatigue process can be captured and reused. Find training Request quote Contact us. Simulate complex loading scenarios using any time domain method static or modal superposition, duty cycles, etc. Processing threads enable you to get finished results from raw inputs in faster.

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

Biaxial 3D Multiaxial Auto-correction. The Thermo-Mechanical Fatigue TMF option provides solvers for high temperature fatigue and creep by using stress and temperature results from finite element simulations. Want to learn more? Enables you to rapidly solve jobs by using the combined processors of many machines.

The following courses feature hands-on examples with DesignLife: Commercial truck owners needing weight and fuel economy savings are considering the benefits of a single wide-base wheel. Duty cycles can be defined by selecting from and building multiple cases. Anys 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.

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. A standard database with fatigue properties for many commonly used materials is included. Download the latest version. The Seam Weld thtorials enables the snsys analysis of seam welded joints including fillet, overlap, and laser welded joints. Select from a pre-populated library of geometries or supply custom stress intensity factors.
