  The composite modeling document shows that the modified hashin damage model is implemented in Autodyn.
  I am attaching the screenshots of the composite modelling document and dropdown for selecting failure in Autodyn.
  The dropdown menu does not contain to hashin. How do I use Hashin with Autodyn.

  Hashin failure model is orthotropic damaged model. It is applied to the materials with orthotropic yielding and failure/damage.
  Hashin failure model is only available in Autodyn Component system or Autodyn Standalone.
  User needs to set the Strength Model to Orthotropic Yield to define the yielding constants and then set Failure Model to Orthotropic Softening. See the pictures attached.
  The description about this material model can be found from ANSYS Help. See attached picture of the Help.

  Thank you cxquan for the answer.
  I want to know what are equations used when we use hashin and puck from workbench and perform impact in Ansys/Explicit.

  Hashin failure model is not available in Workbench Explicit Dynamics system yet.
