Simulation Composite Analysis generates several state variable outputs available for viewing.
In this step, a key variable (SVAR1) is viewed and discussed. SVAR1 is the state variable that tracks fiber and matrix failure within an element.
State variable SVAR1 identifies the discrete damage state of the composite material. To plot this variable, use the PLESOL or PLNSOL commands. The PLESOL contour plot does not average values across element boundaries while the PLNSOL contour plot does average values across element boundaries. Since SVAR1 has discrete values, the PLESOL plot is the most useful. Note, to view SVARs greater than 11, power graphics must be turned off using the /GRAPHICS, FULL command.
The following table lists the three possible values for SVAR1 and the corresponding failure states and contour colors.
To view results in a specific ply (or layer) of the composite plate, use the LAYER command.
Viewing the progression of failure is often useful for visualizing the way a structure fails. Click
or use the SET command to view results at specific points in time.The progression of failure in ply-2 is shown below. As expected, failure initiates at the corners of the notch and progresses laterally towards the edge of the plate until ultimate failure.
