Solid Stresses

Function

  • Check the stress distribution of solid elements in Contours.

 

Call

From the main menu, select [Poshover] tab > [Diagram] group > [Stresses] > [Solid Stress]

 

Input

Pushover-pushover results-stress-solid stress.png

Solid Stresses dialog box


Load Cases/Combinations

Select a desired load case, load combination or envelope case.

Click ....png to the right to enter new or modify existing load combinations. (Refer to "Load Cases / Combinations")

Step
Specify the step for which the analysis results are to be produced. The Step is defined in geometric nonlinear analysis as Load Step, and additional steps are defined in the construction stages of bridges or heat of hydration analyses.

NOTE.png The Construction Stage applicable for the output of the construction stage analysis is defined in Select Construction Stage for Display or Stage Toolbar.

NOTE.pngWhen pushover analysis is performed for a structure containing Plate, Plane Stress or Solid elements, the pushover analysis results for Plate, Plane Stress or Solid elements can be produced by Steps.


Stress Options

Define options necessary to draw the stresses.

Local : Display the stresses with respect to the element's local coordinate system.

UCS : Display the stresses with respect to User Coordinate System.

Element

Display the contour using the element stresses calculated at each node of the elements.

Avg. Nodal

Display the contour using the average nodal stresses of the contiguous elements sharing the common nodes.

Avg. Nodal Active Only

Execute Avg. Nodal for only currently active elements.


Components

Select the desired stress component among the following :

For Local

Sig - xx : Axial stress in the element's local x-direction (Perpendicular to local y-z plane)

Sig - yy : Axial stress in the element's local y-direction (Perpendicular to local x-z plane)

Max-Shear : Maximum shear stress (Tresca Stress)

Sig-eff : Effective stress (von-Mises Stress)

Sig-pmax : Display the maximum numerical value among the absolute values of Sig-P1, Sig-P2 and Sig-P3

Type of Display

Define the type of display as follows:

Contour : Display the stresses of solid elements in contour.

Deform : Display the deformed shape of the model.

Values : Display the stresses of solid elements in numerical values.

Legend : Display various references related to analysis results to the right or left of the working window.

Animate : Dynamically simulate the stresses of the solid elements.

Undeformed : Overlap the undeformed and deformed shapes of the model.

Mirrored : "Mirrored" allows the user to expand the analysis results obtained from a half or quarter model into the results for the full model by reflecting planes.

Yield Point : If the analysis results produced by material nonlinear analysis exceed the yield stress of Plastic Material defined in Initial Uniaxial Yield Stress, Hinge is produced at Gauss Point.

Cutting Plane : Graphically display the stresses of the solid elements along a cutting plane.

IsoSurface : IsoSurface searches and displays the planes of equal stresses resulting from Heat of Hydration analysis within the solid elements.


(Batch Output Generation)

Given the types of analysis results for Graphic outputs, generate consecutively graphic outputs for selected load cases and combinations. A total number of files equal to the products of the numbers of checked items in the three columns of the dialog box below are created.

Batch_Output_Generation___.png : Batch Output Generation : Assign a Base File Name under which the types of results (selection data in the Batch Output Generation dialog box for graphic outputs) are stored.

Batch_Output_Generation___.png : Batch Output Generation : Specify the Base Files to perform Batch Output Generation, construction stages, load cases (combinations), steps, etc. in the following dialog box.

Pushover-pushover results-stress-solid stress-batch.png

Saved Menu-Bar Info's : Listed here are the Base Files. Select the Base File Names for Batch Output.

Delete the selected : Delete all the Base Files selected with the mouse.

When the construction stage analysis is carried out, all the construction stages are listed. We simply select the stages of interests to be included in the batch output. If no construction stage analysis is performed, the column in the dialog box becomes inactive and lists load (combination) conditions.

Stages

The results output of all the construction stages are produced. The construction stages are listed below.

Post CS Loads

The results output for only the Final Stage are produced. The construction stages are listed below. If no construction stage analysis is performed, the load (combination) conditions are listed.

Use Saved

Apply only the (saved) step or load (combination) condition selected at the time of creating each Base File.

Stage LCase/LComb

When the construction stage analysis is carried out, the auto-generated construction stage load conditions and the additionally entered construction stage load combinations are listed. Check on only the load (combination) conditions that will be used to produce batch outputs. This column becomes inactive if "Post CS Loads" is selected or no construction stage analysis is carried out.

Step Option

Specify the steps for which the outputs will be produced when the construction stage analysis or large displacement geometric nonlinear analysis is performed.

Saved Step : Use only the steps used for creating the Base Files

All Steps : Use all the steps


Output Options

Output File Type

Select a Graphic File type, either BMP or EMF.

Auto Description : At the top left of the Graphic Outputs produced in batch, auto-generate and include the notes such as the types and components of the analysis results, construction stages and steps, load (combination) conditions, etc. The font size, color, type, etc. can be changed upon clicking the ....png button.

Output Path

Specify the path for saving the graphic files to be produced in batch.

File Prefix : Specify the prefix of the Graphic Files to be created. The filenames will be consisted of "Prefix"_"Base File Name"_"Load Comb.".bmp(emf) or "Prefix"_"Base File Name"_"Stage"_"Stage LCase"_"Step".bmp(emf).

Make Output : Produce the specified batch Graphic Files reflecting the contents of the dialog box.

Export / Import

Produce the contents of data input in the Base Files and Batch Output Generation dialog box in a binary type file (fn.bog). Click the Import button and select a fn.bog to use the same output format.

NOTE.png Import /Export is only meaningful for different projects. In a given structural model, the Base Files are automatically stored and listed.
