Let’s get acquainted with the material calibration app on the 3DEXPERIENCE platform

An accurate material model is fundamental to correlate finite element analysis results to real world test results. Understanding the Material Calibration app is important for correlation of optimized material values, check fit of the curve and make the best use of FE-based calibration with physics simulations to make your simulation efficient and accurate.

If you are a Material Calibration Engineer or a Structural Mechanics Engineer or a Structural Analysis Engineer, this post will give an introduction to one of the most useful apps on the 3DEXPERIENCE platform for your role.

The Calibrations run using ABAQUS material models:

• ABAQUS possesses powerful capabilities to model advanced non-linear material models.
• These material models can be evaluated quickly without running a full finite element analysis. (FEA).
• Material models are generally represented by equations.

A mathematical model in the context of material representation:

• Uses an equation to capture the constitutive behavior of the model.
• The material response is defined by one or more parameters.
• The number of parameters may change depending on the settings in the material representation.
• The quality of the mathematical model’s fit to the test data depends both on the equation and the parameters.

Categories of material models in the 3DEXPERIENCE model:

• General properties (material damping, density, thermal)
• Linear Elastic
• Elastic-plastic
• Viscoelastic
• Hyperplastic
• Hyperfoam
• Viscoplastic
• Others (fatigue, fluid, injection molding, etc.)

In the next post, we will dive deeper into understanding the nitty-gritty and usage of this app and look at a case study to understand its benefits in the workflow.
