Laminate graphical report

The laminate graphical report generates laminate results that you can display in the Post Processing Navigator. These results are stored in a binary file in the current directory. The graphical report outputs ply results in the ply coordinate system. In post processing, the coordinate system information of ply results is displayed as Coord sys: Native. This indicates that the results are extracted from the solver results file without transformation.

You can set the solver shell stress resultants or the solver ply stresses and strains as the input to the laminate solver for calculating laminate graphical results. For the shell stress resultant as the input, you can select any combination of bottom, middle, and top locations for the ply stress calculation.

The software can graphically display envelopes of the following laminate results:

• Ply stresses and strains

• Ply and bond failure indices

• Ply and bond strength ratios

• Ply and bond margins of safety

The software produces the laminate graphical report from the results sets that you specify for the laminate post report solution process.

Use the Graphical Post Report command to specify the structural data, the laminate results, the enveloping types, and the filtering settings that you want. You can change your specified settings using the Edit command that you access from the graphical report node.

Caution:

• If you rename or edit the laminate graphical report, the Results node in the Simulation Navigator is deleted.

• For stress and strain results displayed using the tensor marker plots, the software gives incorrect orientations.

Enveloping types

For each laminate result, you must specify an enveloping type. The software displays at nodes or elements:

• The maximum and minimum values of the specified laminate results if you select Max & Min.

• The minimum values of the specified laminate results if you select Min.

• The maximum values of the specified laminate results if you select Max.

• The maximum absolute values of the specified laminate results if you select Max Absolute.

• The minimum absolute values of the specified laminate results if you select Min Absolute.

Enveloped results

You can generate the following enveloped results:

• Ply results over all load cases. You can see the critical load case ID for each ply.

• Elemental results over all plies and over all load cases. You can see the critical ply and load case ID.

• Elemental results over all plies for each load case. You can see the critical ply ID for each load case.

You can also generate the following non-enveloped results: ply results for each load case. This is useful when starting from 2D element shell resultants and therefore in the absence of ply results from the structural solver.

Changing the ply and interlaminar failure theories in post processing

In the Simulation file, you can choose the ply and interlaminar failure theories, or change them if they are defined in the FEM. You can select one or two different failure theories to generate a graphical report and compare the results. When you choose a different theory, either for the ply or the interlaminar failure theory, the software generates additional results when you request the following outputs:

• Failure index

• Strength ratio

• Margins of safety
