Elastoplastic Material Modeling
This chapter provides information from preparing data to generating a material card.
- Basic Settings
  To get started configure these basic settings.
- Prepare Raw Data
  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
  Import data files from your local system.
- Import Data from AMDC
  Import data files from Altair Material Data Center (AMDC) to AMM.
- Prepare Data
  Each file in the list can be edited individually.
- Curve Fitting
  Each prepared curve is displayed in the Curve Fitting list. Select the desired curve for fitting.
- Extrapolation
  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.
- Generate Material Card
  Define the material solver card properties to create a material card.
- Advanced Material Modeling
  The chapter provides information on the advanced details such as strain rate, failure, and simulation for a model.
- Side Toolbar
  Use the toolbar keys to save the session with configurations applied, reload, export curves, quit, and finish.
Multi-Physics Material Modeling
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.
