Calibrate Nitinol Material Behavior Abaqus Plugin

Calibrate Nitinol Material Behavior Abaqus Plugin

The Calibrate Nitinol Material Behavior Abaqus Plugin is designed to calibrate the superelastic and superelastic-plastic behaviors of Nitinol material for use in Abaqus/Standard or Abaqus/Explicit analyses.

The plugin provides a user-friendly interface that allows users to create Nitinol material parameters based on uniaxial tension test data. It automatically generates the necessary keywords and data lines based on a few characteristic points selected from the test data. The material is then renamed according to the required naming convention for Nitinol, making it ready for direct use within Abaqus/CAE.

Additionally, the Calibrate Nitinol Material Behavior plugin offers an option to evaluate the material definition by running a uniaxial 3D one-element model analysis. If this option is selected, the plugin submits the analysis and plots the results alongside the original test data for comparison. This enables the user to iterate the process by editing the selected data points until the desired material behavior is achieved.
