ANSYS nCode DesignLife Capabilities

Ease of Use

By leveraging the direct connection from geometry to analysis to completed fatigue study, you can accelerate the development process to deliver world class products. Parametric analysis produces complete analysis results for a series of design variations at the click of a mouse. Using this workflow process and performing parametric simulations, you can optimize a complex structure for the desired product life — and save valuable engineering and design time. It’s also easy to set up fatigue life optimization using the ANSYS Workbench integrated DesignXplorer.

Extensive Fatigue Material Library

Fatigue modeling relies heavily on material data to predict the life and damage of components during their lifetime. ANSYS nCode DesignLife comes with a comprehensive material library covering a wide range of metals: aluminum, steel, titanium, copper and cast Iron are included as part of the standard installation. Many materials include variations of properties to take into account the rolling, forging and casting of the raw material.

An optional premium material library is also available to include more exotic and recently tested materials in your simulations.

State-of-the-art Fatigue Modeling Capabilities

For calculation of fatigue life and fatigue damage using either a strain-life-based method for low cycle fatigue analysis or stress life for high cycle fatigue, you can understand how parts and assemblies will behave under loading conditions beyond single loading scenarios.

You can also use the Dang Van criterion to take into account the microscopic stresses and strains within critical grains and calculate the endurance limit as a safety factor.

ANSYS nCode DesignLife calculates non-proportionality and the biaxial ratio, and then selects the best method to use when performing calculations.

Hot-spot detection identifies critical areas automatically, so you can zoom in on problematic regions, identify the source of failure quickly and implement fixes.

Seam welds can be modeled and fatigue life can be accurately calculated including filet, overlap and laser welded joints. This method is appropriate for weld toe, root and throat failures.

ANSYS nCode DesignLife can also simulate a virtual shaker table test environment that could be used for test and material calibration.

Composite materials can also be analyzed using ANSYS nCode DesignLife with industry standard failure criteria.
