This chapter provides information from preparing data to generating a material card.
The chapter provides information on the advanced details such as strain rate, failure, and simulation for a model.
Here are two different criteria for generating failure.
Generating accurate material properties can be a time-consuming process, Altair Material Modeler (AMM) is a sophisticated modeling software that efficiently processes material data from testing to generate simulation-ready material cards for analyzing the nonlinear behavior of bulk materials as well as the various physical properties of materials, such as polymers and elastomers, used in the manufacture of modern products.
Here’s a quick look at the latest features available with Altair Material Modeler.
Discover the features of Altair Material Modeler with interactive tutorials.
To get started configure these basic settings.
To facilitate effective management of multiple files of test results, you should structure the raw data by format before importing it into AMM.
Import data files from your local system.
Import data files from Altair Material Data Center (AMDC) to AMM.
Each file in the list can be edited individually.
Each prepared curve is displayed in the Curve Fitting list. Select the desired curve for fitting.
AMM provides multiple mathematical models for curve fitting and extrapolation according to solver requirements. Additionally, the expert mode enables you to create strain-rate curves, failure criteria, and run validation simulations.
Define the material solver card properties to create a material card.
Enhance the model testing by performing the advanced modeler to generate strain rates, failure, and a simulation run.
If strain-dependent tests have been performed (tensile tests at different velocities) and the curves are available, you can include strain rate dependencies.
If failure dependent tests have been performed (tension, shear, compression tests) and the information is available, to include failure criteria in the curves fit.
This failure model uses a simplified nonlinear, strain-based, failure criteria with linear damage accumulation. The failure strain is described by two parabolic functions calculated using curve fitting from up to 5 user-defined failure strains.
The validation run is supported for Radioss only and it provides a quick overview of your material card.
Use the toolbar keys to save the session with configurations applied, reload, export curves, quit, and finish.
Altair Material Modeler is a collection of data fitting tools for polymers in a single cohesive studio environment with a workflow designed around using the results for various manufacturing and structural simulations including injection molding, extrusion, temperature-dependent structural simulation, short fiber multiscale modeling, and hyperelastics.
