Contours the shear strain occurring in the in-filling material of DD elements.

This component can be accessed via the Strength Factor Components toolbar as follows:

 

clip0309

 

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 clip0310 button on the Contours toolbar activates the Surface Components toolbar.

 

clip0312

 

The shear strain is determined by dividing the shear displacement (ride) by the DDplane thickness.

Note that there are three components of strain that can be contoured:

 

ID_PLOT_STRAIN_ELASTIC Plot > Surface Components > Value > Elastic

ID_PLOT_STRAIN_PLASTIC Plot > Surface Components > Value > Plastic

ID_PLOT_STRAIN_TOTAL Plot > Surface Components > Value > Total

 

There are also two different ways of presenting the strain:

 

ID_PLOT_STRAIN_INDUCED Plot > Strain > Value > Induced Strain

ID_PLOT_STRain_ABSOLUTE Plot > Strain > Value > Absolute Strain

 

Note that ID_SURFACE_SHEAR_STRAIN is the current level of shear strain acting on the DD surfaces.

 

Since the displacement can change direction and even reverse during slip, the total accumulated shear strain ID_SURFACE_ACCUMULATED_STRAIN can give different values.

 

The contour range is set using

 

ID_RANGE Plot > Range

 

This component can be added to the contour toolbar if desired
