Figure 17.1: Discrete Reinforcing Modeling Option


Use the smeared option (SECTYPE,SECID,REINF,SMEAR) for modeling reinforcing fibers that appear in
layered form. ANSYS treats one layer of fibers with identical material, orientation, and cross-section area
as a homogeneous membrane having unidirectional stiffness, as shown:

For detailed information about the reinforcing options, see the documentation for the REINF264 and
REINF265 elements, and REINF264 - 3-D Discrete Reinforcing and REINF265 - 3-D Smeared Reinforcing
in the Mechanical APDL Theory Reference.


17.3. Defining Reinforcing Sections and Elements


Use the following general process to create reinforcing elements:



  1. Create the base elements.

  2. Build the reinforcing sections.

  3. Select the base elements that you want to reinforce.

  4. Generate the reinforcing elements from the base elements (EREINF).

  5. Inspect and verify the newly created reinforcing elements.


Reinforcing elements ignore any subsequent modifications made to the base elements. ANSYS, Inc. re-
commends issuing the EREINF command only after you have finalized the base elements. If you delete
