Contours the maximum shear strain acting on ubiquitous plane #1, and the strain component normal to this plane. These components can be accessed via the Strain Components toolbar as follows:
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 You can add this button to the Contours toolbar using the configuration
To calculate the ubiquitous strains, the strain state at each point on the grid plane is reoriented to determine the maximum shear strain parallel to the ubiquitous plane and the strain normal to the ubiquitous plane. Note that εnu is oriented normal to the ubiquitous plane and is not parallel to the direction of a line grid.
•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 orientation of the ubiquitous shear plane is set using
Note that there are three components of strain that can be contoured:
There are also two different ways of presenting the strain:
The contour range is set using
This component can be added to the contour toolbar if desired
The user may find it handy to add the
button to the contouring toolbar for quick access to all strain components.
