The Plastic Curve Generator Plugin

The Plastic Curve Generator plugin helps the Abaqus user to create plastic curves easily. The input data can be either: engineering stress-strain curves, true total stress-strain curves, or true plastic strain-stress curves. it makes automatically all the conversions needed from the input data, giving the user the total true curve, plastic curve, and output curve, which is obtained according to the selected law. The laws available are:

• Hollomon
• Ludwik
• Johnson Cook
• Swift
• Krupkowski
• Ramberg-Osgood
• Ramberg-Osgood Simplified
• Ramberg-Osgood Modified
• Hockett-Sherby ¹
• Hollomon Linear Constant (HLC) ¹

Plastic Curve Generator Plugin for Abaqus

The Plastic Curve Generator plugin allows Abaqus users to plot the curves calculated against input data to have a visual comparison and give information about the error, R-square, and Chi-Square (depending on the selected law). In addition, gives the Abaqus user the law parameters.

Different ways to obtain the parameters are implemented in the Plastic Curve Generator plugin and for Hockett-Sherby and HLC laws, the plugin makes it easy for the Abaqus user tool to create the specimen to be simulated.

Is a good complement to define material properties for metal forming simulations, like bending simulations coming from the Bending Pipe plugin.

Who this plugin is for:

• Engineering or science students and professionals who need to calibrate metal test data for Abaqus simulations
• Advanced students, Ph.D. students, or researchers for their Abaqus FEA projects
• Any Abaqus Application Engineer who is involved with various simulation projects on a daily basis
