  • Check the stress distribution of plane-stress elements or plate elements in Contours for each Pushover Step, based on the pushover analysis results.

 

Call

From the main menu, select [Poshover] tab > [Diagram] group > [Stresses] > [Plane-Strain Stress]

 

Input

Pushover-pushover results-stress-plane stress plate stress.png

Plane-Stress/Plate 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 heat of hydration analysis etc.

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.png When 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 : For planar elements, which are placed parallel with the x-y plane of a User Coordinate System, resulting stresses are displayed relative to the UCS. If no UCS has been defined, the Global Coordinate System is assigned.

Print UCS Axis : Check on to print the UCS axes on the output.

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.

Top

Display stresses at the top side of plate elements. The top side refers to the upper extreme fiber in the element's local z-direction.

Bottom

Display stresses at the bottom side of plate elements. The bottom side refers to the lower extreme fiber in the element's local z-direction.

Both Sides

Display simultaneously stresses at the top and bottom sides considering the thickness of the plate elements. The stresses through the thickness of the plate elements are linearly interpolated.

Abs Max

Display only the maximum absolute values of the stresses at the top and bottom surfaces.


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)

Sig - xy : Shear stress in the element's local x - y plane (In-plane shear stress)

Vector : Display the maximum and minimum principal stresses in vectors

Vector Scale Factor : Drawing scale for the vector diagram

                                           Sig-xx                                Sig-yy                              Sig-xy

For UCS

Sig-xx : Axial stress in the direction of the user coordinate system's x-axis.

Sig-yy : Axial stress in the direction of the user coordinate system's y-axis.

Sig-zz : Axial stress in the direction of the user coordinate system's z-axis.

Sig-xy : Shear stress in the x-y plane of the user coordinate system.

Sig-yz : Shear stress in the y-z plane of the user coordinate system.

Sig-xz : Shear stress in the z-x plane of the user coordinate system.

Sig-max : Maximum Principal Stress

Sig-min : Minimum Principal Stress

Sig-eff : von-Mises Stress

Max-Shear : Maximum shear stress (Tresca Stress)


Type of Display

Define the type of display as follows :

Contour : Display the stresses of plane-stress/plate elements in contour.

Deform : Display the deformed shape of the model.

Values : Display the stresses of plain-stress/plate 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 plain-stress/plate 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 Diagram : Graphically display the stresses of the plain-stress/plate elements along the cutting line or plane.


Value Option

When the contour output method is set to "Element," you can select the value output method. If the contour output method is set to "Avg.Nodal," it will output the maximum value among the averaged nodal results.

Max : Output the maximum value among the nodal results.

Element Center : Output the result value at the element center.


(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-plane stress plate 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.
