How To Use "View Cut" And "Input File" To Draw The Bending Moment And Shear In Abaqus?

Postprocessing

Switch to the Visualization module, and open the file Crane.odb. Abaqus displays an undeformed shape plot of the crane model.

Plotting the deformed model shape

To begin this practice, plot the deformed model shape with the undeformed model shape superimposed on information technology. Specify a nondefault view using (0, 0, 1) as the Ten-, Y-, and Z-coordinates of the viewpoint vector and (0, 1, 0) as the X-, Y-, and Z-coordinates of the upward vector.

The undeformed shape of the crane superimposed upon the plain-featured shape is shown in Figure one.

Using display groups to plot chemical element and node sets

You can use display groups to plot existing node and chemical element sets; you can also create brandish groups by selecting nodes or elements directly from the viewport. Yous will create a display group containing only the elements associated with the main members in truss construction A.

To create and plot a display group:

1. In the Results Tree, expand the Sections container underneath the output database file named Crane.odb.

2. To facilitate your selection, modify the view back to the default isometric view using the tool in the Views toolbar.

3. In succession, click the items in the container until the elements associated with the main members in truss A are highlighted in the viewport. Click mouse button 3 on this particular and select Replace from the menu that appears.

   Abaqus/CAE at present displays merely this grouping of elements.

4. To salvage this group, double-click Display Groups in the Results Tree; or use the tool in the Brandish Group toolbar.

   The Create Display Grouping dialog box appears.

5. In the Create Display Grouping dialog box, click Save As and enter MainA as the name for your display group.

6. Click Dismiss to shut the Create Display Grouping dialog box.

   This brandish grouping now appears underneath the Display Groups container in the Results Tree.

Beam cantankerous-section orientation

You volition at present plot the section axes and axle tangents on the undeformed model shape.

To plot the beam section axes:

1. From the chief bill of fare bar, select ; or use the tool in the toolbox to display simply the undeformed model shape.

2. From the main carte bar, select ; then, click the Normals tab in the dialog box that appears.

3. Toggle on Show normals, and take the default setting of On elements.

4. In the Style area at the bottom of the Normals page, specify the Length to be Long.

5. Click OK.

   The section axes and beam tangents are displayed on the undeformed shape.

The resulting plot is shown in Figure 2. The text annotations in Figure 2 that identify the section axes and beam tangent will not appear in your image. The vector showing the local axle 1-centrality, ${\mathbf{north}}_{\mathrm{one}}$ , is blue; the vector showing the beam 2-axis, ${\mathbf{n}}_{\mathrm{ii}}$ , is red; and the vector showing the beam tangent, $\mathbf{t}$ , is white.

Rendering beam profiles

You will now brandish an idealized representation of the beam contour and contour the stress results.

To render beam profiles:

1. From the master menu bar, select .

   The ODB Brandish Options dialog box appears.

2. In the General tabbed page, toggle on Render beam profiles and accept the default scale factor of 1.

3. Click OK.

   Abaqus/CAE displays beam profiles with the appropriate dimensions and in the correct orientations. Figure 3 shows the beam profiles on the whole model. Your changes are saved for the duration of the session.

4. Click to contour the Mises stress on the rendered contour.

Creating a hard copy

You can save the current prototype to a file for hard-copy output.

To create a PostScript file of the current image:

1. From the master menu bar, select .

   The Impress dialog box appears.

2. From the Settings expanse in the Print dialog box, select Black&White equally the Rendition blazon; and toggle on File equally the Destination.

3. Select PS as the Format, and enter beam.ps as the File name.

4. Click .

   The PostScript Options dialog box appears.

5. From the PostScript Options dialog box, select 600 dpi as the Resolution; and toggle off Print appointment.

6. Click OK to utilize your selections and to close the dialog box.

7. In the Print dialog box, click OK.

   Abaqus/CAE creates a PostScript file of the current image and saves it in your working directory as beam.ps. You can impress this file using your system's command for printing PostScript files.

Displacement summary

Write a summary of the displacements of all nodes in brandish group MainA to a file named crane.rpt. The peak displacement at the tip of the crane in the two-direction is 0.0188 m.

Section forces and moments

Abaqus can provide output for structural elements in terms of forces and moments interim on the cross-section at a given signal. These section forces and moments are defined in the local beam coordinate system. Toggle off the rendering of beam profiles, so contour the section moment nearly the beam 1-axis in the elements in display group MainA. For clarity, reset the view so that the elements are displayed in the 1–2 plane.

To create a "bending moment"-type contour plot:

1. From the list of variable types on the left side of the Field Output toolbar, select Main.

2. From the list of output variables in the heart of the toolbar, select .

   Abaqus/CAE automatically selects , the outset component name in the list on the correct side of the Field Output toolbar, and displays a contour plot of the bending moment about the axle 1-axis on the deformed model shape. The deformation scale factor is chosen automatically since geometric nonlinearity was non considered in the assay.

3. Open the Common Plot Options dialog box, and select a Uniform deformation scale cistron of 1.0.

   Colour contour plots of this type typically are not very useful for one-dimensional elements such equally beams. A more than useful plot is a "bending moment"-type plot, which you tin produce using the contour options.

4. From the main carte du jour bar, select ; or apply the Contour Options tool in the toolbox.

   The Contour Plot Options dialog box appears; past default, the Bones tab is selected.

5. In the field, toggle on Show tick marks for line elements.

6. Click OK.

   The plot shown in Effigy 4 appears. The magnitude of the variable at each node is at present indicated by the position at which the contour curve intersects a "tick mark" drawn perpendicular to the element. This "bending moment"-type plot can be used for any variable (not just bending moments) for any one-dimensional element, including trusses and axisymmetric shells besides as beams.
