Fatigue Life Prediction and Test-CAE Correlation

Predict structural durability from major FEA results

nCode DesignLife is a CAE-based fatigue analysis system that contains a comprehensive set of solvers and advanced methods for predicting structural durability from major finite element analysis (FEA) result files. It identifies critical locations and calculates realistic fatigue lives for both metals and composites. Design engineers can go beyond performing simplified stress analysis and avoid under- or over-designing products by simulating actual loading conditions to avoid costly design changes.

Discover key capabilities in DesignLife for efficiently locating critical failures

Avoid over-designing and costly changes


Simulate actual loading conditions based on FEA results from leading solvers such as ANSYS, Nastran, Abaqus, Altair OptiStruct, LS-Dyna and others.

Improve consistency and quality of analysis


Intuitive, graphical interface with functions for multiaxial, welds, short-fibre composite, vibration, crack growth, thermo-mechanical fatigue and more

Increase confidence in results of simulations


Perform smarter, quicker physical tests by correlating CAE directly with physical test data in a single environment.

Achieve more accurate fatigue estimation


Reduce cost and weight by assessing more designs with material parameters derived from in-house materials testing.

Rapidly improve product designs with faster analysis


Improve simulation throughput by leveraging hardware scalability with multi-threaded and distributed processing capabilities for processing large finite element models.

Improve and optimize the durability of composite components


Understand performance of new materials with composite-focused modules capable of modeling structural performance and possible failure modes, including fatigue.

High quality fatigue parameters

 

The Premium Materials Database contains over 100 fatigue properties primarily for commonly used types of steel and aluminium alloys, plus some other nonferrous materials. These high-quality fatigue parameters include statistical estimates of scatter to enable reliability and certainty of survival to be assessed.

Fatigue characterisation and material testing

 

In order to achieve the closest fatigue estimation for design, we recommend using material parameters from material tested in the exact condition. This means using the composition, manufacturing route, and heat treatment condition (including strength) that is directly relevant to the component. These parameters should ideally come from test coupons machined from an actual component.

FEA fatigue analysis in the HBK Advanced Materials Characterization & Test facility (AMCT)
.. engineers are using nCode DesignLife, for instance, to analyze hood slams. After gathering data from three slam velocities, the engineers can run the stress time history through nCode DesignLife to determine the number of cycles required to induce cracking. With this process, nCode DesignLife saves both cost and time in the testing.

"The ability to evaluate design options and if necessary change the design in the early stages of the design process increases confidence, reduces risk and helps get products to market faster."
