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:
- Create the base elements.
- Build the reinforcing sections.
- Select the base elements that you want to reinforce.
- Generate the reinforcing elements from the base elements (EREINF).
- 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
