Biaxial 3D Multiaxial Auto-correction Mean stress corrections: Simulate complex loading scenarios using any time domain method static or modal superposition, duty cycles, etc. DesignLife provides methods to intelligently identify weld lines in the FE model, thus simplifying the process of setting up a fatigue job. The Adhesive Bonds option enables durability calculations on adhesive joints in metallic structures.
Safety Factor enables the calculation of stress based factors of safety. Stresses from a complete finite element model are analyzed in a single analysis process.
A standard database with fatigue properties for many commonly used materials is included.
Introduction to ANSYS nCode DesignLife – FEA, CFD and Explicit Dynamics
Includes new optimised and spot weld methods. The following courses feature hands-on examples with DesignLife: Material inputs are standard mean stress corrections or user-specified Haigh diagrams to assess durability.
Uses specific material parameters calculated from tensile and torsion tests. 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.
Vibration Manager Enables vibration specification data to be entered, edited, and viewed. Includes the ability to interpolate multiple material data curves for factors such as mean stress or temperature.
Fatigue analysis process Once created, the fatigue process can be captured and reused. The following methods ncodr be used individually or combined to give the most conservative result: Time histories due to applied loads can be extracted for direct correlation with your measured strain or displacement data. High temperature fatigue methods: 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.

The Composite Analysis option allows users to evaluate the strength of a structure against industry standard composite failure criteria. Engineers without fatigue expertise can evaluate modified product designs drsignlife determine the updated product life. Distributed Processing enables a DesignLife analysis running in batch mode to be distributed across multiple computers or nodes of a computer cluster.
Animating displacements from FE results or animation files display structural deformation under load.

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.
ANSYS nCode DesignLife contains the most up-to-date methods and simulation tutoriaos to make predicting fatigue life as accurate and easy as possible.
This allows critical locations, load combinations and associated design reserve factors to be readily identified. Manufacturing effects can be accounted for by using equivalent plastic strain in the unloaded component.
Duty cycles can be defined by selecting from and building multiple cases. 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. Rather ndode 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. This feature makes it easy to create a composite duty cycle with repeats.
Enables you to rapidly solve jobs by using the combined processors of many machines. The primary application of the Stress-Life SN method is high-cycle fatigue long lives where nominal stress controls the fatigue life.
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 anyss.
