3.2 Problem description

The results from the analysis defined in section 2 are read in to FEMVIEW and presented in a number of different ways.

Having started FEMGV :-

Step 1

Prepare the model

Read the mesh and results into FEMVIEW.

UTILITY READ VIEWDATA train1.fvi

Select FEMVIEW with the jobname TRAIN1 and display the outline view.

FEMV TRAIN1

Step 2

Check displacements results

Find out what loadcases and results exist.

UTILITY TABULATE LOADCASES

The first loadcase has automatically been selected.

Select resultant nodal displacements to be viewed.

RESULTS NODAL DI ALL

VIEW MESH

Look at the displaced shape.

PRESENT SHAPE

Figure 3.1: Displacement shape

Step 3

Contour Stresses

Select nodal stresses in the X direction.

RESULTS NODAL ST S11

Show the stress contours in ten steps.

PRESENT CONTOUR LEVELS

Scale the mesh to fit the frame.

Step 4

Look at Von Mises Stresses

Calculate Von Mises stresses.

RESULTS CALCULATE VONMISES

Show contours of the stresses.

PRESENT CONTOUR LEVELS

Show the actual values at the nodes.

PRESENT NUMERIC

Show the location of the minimum and maximum values.

PRESENT PEAKS

Step 5

Draw a graph

Put the node numbers on the mesh.

LABEL MESH NODES

Zoom in using the mouse/cursor to define two diagonally opposite corners of a rectangle containing the circle.

EYE ZOOM IN .

Select a number of nodes around the hole

CONSTRUCT LINE NODE LIST 48 49 50 51 52 37 38

Draw a graph of the variation of the stress (VON MISES in this case) between the nodes specified.

PRESENT GRAPH LINE OLD

Step 6

Stop the program

STOP!

STOP

Confirm STOP.
