This allows you to contour the maximum ID_PLOT_STRESS_INPLANEMAX and minimum ID_PLOT_STRESS_INPLANEMIN stresses tangential to the currently selected grid plane or perpendicular to a line grid.

These components can be accessed via the Stress Components toolbar as follows:

 

clip0288

 

This toolbar can be changed to a vertical orientation by dragging is against either the right or left hand edge of the main window.

It can be changed back to a horizontal orientation by dragging is against either the top or bottom edge of the main window.

 

Selecting the clip0290 button on the Contours toolbar activates the Stress Components toolbar.

 

clip0291

 

To calculate the maximum and minimum in-plane stresses, the stresses tangential to the grid plane are determined, then resolved to give the maximum and minimum values. Note that σip is oriented normal to the grid plane and parallel to the direction of a line grid. Also note that σip, σ1i and σ3i are perpendicular to one another.

 

dip direction is measured positive clockwise from the y-axis.

dip of the plane is measured positive down from the horizontal (i.e. the dip direction).

plunge of the normal is measured positive down (i.e. negative up) from the horizontal.

 

The contour range is set using

 

ID_RANGE Plot > Range

 

This component can be added to the contour toolbar if desired

 

ID_VIEW_BAR_OPTIONS Tools > Configure Contouring Toolbar > Stress

 

The user may find it handy to add the

 

ID_PLOT_STRESS_SPECIAL More Stress Components

 

button to the contouring toolbar for quick access to all stress components.
