This chapter walks through the new Material Modeler, web-based environment and introduces the steps required to model hyperelastic materials using AMM by creating projects , adding a material and a quasi-static workflow, importing data, fitting the available models, and finally saving the state and exporting fitted data for CAE analysis.
Add Workflow
Set up model workflows to evaluate physical behavior.

- View Dashboard
  Dashboard provides logged in user information, application build and version, and recent projects. You can also create a new project from this page. If the user prefers a dark theme, it is available via the icon in the upper right corner.
- Projects
  Projects are a way of collecting what has been done for one or more materials. Depending on a specific customer's need, a project might contain one material or all the materials used in a sub-assembly (e.g. a truck door) or a full product (e.g. a coffee maker). Create, open, share,and manage new projects on this page. A project contains the project's name, the Author (registered user who created the project), Type (user definable), Email & Phone to contact the project's author, and any notes pertaining to the project.
- Add Material
  Create material entries before importing test data or applying models.
- Add Data
  Upload experimental test data to characterize the material.
- Add Workflow
  Set up model workflows to evaluate physical behavior.
- Add Plot Data
  Visualize raw input data before model fitting.
- Export CAE Card
  Generate material cards for integration with CAE solvers.

Add Workflow

Set up model workflows to evaluate physical behavior.

Add Objective Workflow

Under the material, click + Add Workflow.
Choose Objective Workflow.
Enter a Name based on the test scope.
Select applicable test types from the list (e.g., tension, shear).

Specifying the Physics Workflow

Navigate to the Physics Workflow tab.
Select a predefined template (e.g., Hyperelastic, Viscosity).
Review the preconfigured stages.

Models Available

The current Physics Workflow is "Quasi-Static" and the only material type available is Hyperelastic. The models available include :

NeoHookean: Models shear-thinning behavior at constant temperature.
Mooney-Rivlin: Mooney-Rivlin can have 2, 5, or 9 parameters..
Arruda-Boyce:
Gent:
Signorini:
Yeoh:
Ogden (Type 1, N=2 to N=6):
Ogden (Type 2, N=2 to N=6):
