Figure 17.5: Fiber Orientation Display on Smeared Reinforcing Elements
17.4. Reinforcing Simulation and Postprocessing
The REINF264 and REINF265 reinforcing elements have plasticity, stress stiffening, creep, large deflection,
initial stress, and large strain capabilities. You can use them in any type of simulation that their base
elements support.
Reinforcing elements allow tension-only (cable) and compression-only (gap) options. You can specify
those options via the SECCONTROL command. A nonlinear iterative solution procedure is necessary
for simulating the tension-only or compression-only behaviors.
Reinforcing elements always list or display stress and strain results in local fiber directions. Therefore,
the coordinate system specified via the RSYS command has no effect. Reinforcing results display is
supported in both PowerGraphics and FullGraphics. In PowerGraphics mode, all reinforcing fibers (discrete)
or layers (smeared) are displayed shown concurrently. In FullGraphics mode, however, only one reinforcing
fiber or layer can be displayed at one time. T o specify the desired layer or fiber to display in
FullGraphics mode, issue the LAYER command.
You can perform a failure analysis on the reinforcing elements. For more information, see Specifying
Failure Criteria for Composites (p. 413).
