Find information about material data blocks in GRF files.
Material Models
HyperXtrude associates each component with a material. Each material is defined inside the material data block in the GRF file.
Workpiece Material Properties
The Workpiece material is used to describe the extrudate in metal extrusion. Typically, this material is applied to the components in the mesh that describe the negative volume created by the tool (such as, billet, pockets, feeder cavity, welding chamber, porthole etc.) Inside the user profile, we assign this material even to the boundary faces of the workpiece components. HyperXtrude supports the following constitutive models for metals:
Hensel Spittel Model
Temperature, strain, and strain rate dependent Hensel Spittel model used in HyperXtrude is given by the following expression. It has a built-in temperature dependence in the equation and it is used all the time.

- What is Inspire Extrude Metal?
  Inspire Extrude Metal offers an analysis tool for virtual testing, validation, correction and optimization of extrusion die designs.
- FAQs
  Find answers to Frequently Asked Questions from our users.
- Extrusion Analysis
  Setup and perform an Extrusion analysis.
- Tool Deflection Analysis
  Setup and perform a Tool Deflection analysis.
- Design Explorer
  Evaluate designs by using geometric variables and applying a design-of-experiments (DOE) or optimization method. We recommend fully constraining your sketch when sketch variables are used in the design exploration.
- Quenching Analysis
  Setup and perform a quenching analysis.

  - Material Models
    HyperXtrude associates each component with a material. Each material is defined inside the material data block in the GRF file.
    - Assign Material properties
      This block of information is for assigning the material properties to each element MATID.This block also enables you to identify different regions of the mesh with a unique name so as to use it for post-processing or mesh adaptation. A single MATERIAL can be assigned to more than one MATID.
    - Fluid Material Properties
      The Fluid material type is a parameter used with the BEGIN MATERIAL data block.
    - Workpiece Material Properties
      The Workpiece material is used to describe the extrudate in metal extrusion. Typically, this material is applied to the components in the mesh that describe the negative volume created by the tool (such as, billet, pockets, feeder cavity, welding chamber, porthole etc.) Inside the user profile, we assign this material even to the boundary faces of the workpiece components. HyperXtrude supports the following constitutive models for metals:
      - Sine Hyperbolic Inverse Model
        The Sine Hyperbolic Inverse model is given by the following expression.
      - Metal Forming Power Law
        The generalized power law used in HyperXtrude is given by the following expression.
      - Norton-Hoff Model
        Temperature, strain, and strain rate dependent Norton-Hoff model used in HyperXtrude is given by the following expression.
      - Hensel Spittel Model
        Temperature, strain, and strain rate dependent Hensel Spittel model used in HyperXtrude is given by the following expression. It has a built-in temperature dependence in the equation and it is used all the time.
    - Polymer Material Properties
      HyperXtrude supports six different models to describe the constitutive behavior of polymers. The material models available in HyperXtrude are:
    - Solid Material Properties
      The Solid material type is a parameter used with the BEGIN MATERIAL data block. This material must be used when solving conjugate heat transfer problems.
    - Tool Material Properties
      The Tool material type is similar to the Solid material type and is a parameter used with the BEGIN MATERIAL data block. This material must be used when solving conjugate heat transfer problems. For Tool, HyperXtrude allows you to specify the conductivity in the form of diagonal tensor.

Hensel Spittel Model

Temperature, strain, and strain rate dependent Hensel Spittel model used in HyperXtrude is given by the following expression. It has a built-in temperature dependence in the equation and it is used all the time.

σ_{f} = A \cdot e^{m_{1} T} \cdot ε^{m_{2}} \cdot {\dot{ε}}^{m_{3}} \cdot e^{m_{4} / ε} \cdot (1 + ε)^{m_{5} T} \cdot e^{m_{7} ε} \cdot {\dot{ε}}^{m_{8} T} \cdot T^{m_{9}}


A	Material Constant (`Pa`)
`m`₁...`m`₈	Material constants (dimensionless)
$\dot{ε}$	Effective strain rate (`s`^-1)
ε	Effective strain
`T`	Temperature (K)
σ_f	Flow stress (`Pa`)
